Exponential numbers powers

To raise an exponential number to a power, raise both the coefficient to the power and the exponential part to the power. To do the latter, multiply the original exponent by the power ... [Pg.16]

Lifetime heterogeneity can be analyzed by fitting the fluorescence decays with appropriate model function (e.g., multiexponential, stretched exponential, and power-like models) [39], This, however, always requires the use of additional fitting parameters and a significantly higher number of photons should be collected to obtain meaningful results. For instance, two lifetime decays with time constants of 2 ns, 4 ns and a fractional contribution of the fast component of 10%, requires about 400,000 photons to be resolved at 5% confidence [33],... [Pg.133]

The shape of the size distribution function for aerosol particles is often broad enough that distinct parts of the function make dominant contributions to various moments. This concept is useful for certain kinds of practical approximations. In the case of atomospheric aerosols the number distribution is heavily influenced by the radius range of 0.005-0.1 /xm, but the surface area and volume fraction, respectively, are dominated by the range 0.1-1.0 fxm and larger. The shape of the size distribution is often fit to a logarithmic-normal form. Other common forms are exponential or power law decrease with increasing size. [Pg.59]

Exponential notation enables easy reporting of extremely large and extremely small numbers. A number in scientific notation consists of a coefficient times 10 to an integral power, where the coefficient is equal to or greater than 1 but less than 10. Learn how to convert numbers from exponential notation to ordinary decimal values, and vice versa, and also how to use exponential numbers in calculations. Also learn to use effectively an electronic calculator with exponential capability (see Appendix 1). (Section 2.2)... [Pg.78]

When an old friend of ours was writing a note asking for a favour, he usually finished the note with the phrase Thanks a 10 . That expression, 10 , spoken as ten to the sixth or ten to the power six , is the scientific way of saying one million , and is known as an exponential number, or a number written in standard form, Le. one expressed in powers of 10. [Pg.122]

A logarithm (or log) of a number is the power to which some base number (usually 10) must be raised in order to give the desired number. Thus, a logarithm is an exponent of the base 10. From the discussion in the previous paragraphs about exponential numbers, we can draw the following conclusions with respect to logs ... [Pg.1069]

The key point is that as the number of qubits increases, the dimensionality of the Hilbert space grows exponentially. In some sense, we can store an exponential number of classical configurations, which - if we can manipulate them - can give us access to vast computational power. [Pg.18]

To take the power, root, or reciprocal of an exponential number, enter the number first, then press the appropriate key or keys. For example, the square root of 5.6 X 10 is obtained as follows ... [Pg.787]

It is inconvenient to be limited to decimal representations of numbers. In chemistry, very large and very small numbers are commonly used. The number of atoms in about 12 grams (g) of carbon is represented by 6 followed by 23 zeros. Atoms typically have dimensions of parts of nanometers, i.e., 10 decimal places. A far more practical method of representation is called scientific or aqponential notation. A number expressed in scientific notation is a number between 1 and 10 which is then multiplied by 10 raised to a whole number power. The number between 1 and 10 is called the coefficient, and the factor of 10 raised to a whole number is called the exponential factor. [Pg.14]

You can use a calculator to add and subtract numbers in exponential notation without first converting them to the same power of ten. The only thing you need to be careful about is entering the exponential number correctly. I m going to show you how to do that right now ... [Pg.335]

In multiplication and division of exponential numbers, the digital portions of the numbers are handled conventionally. For the powers of 10 in multiplication exponents are added algebraically, whereas in division the exponents are subtracted algebraically. Therefore, in the preceding example,... [Pg.14]

To add or subtract exponential numbers without a calculator, you need to align digit values (hundreds, tenths, units, and so on) vertically. This is done by adjusting coefficients and exponents so all exponentials are 10 raised to the same power. The coefficients are then added or subtraeted in the usual way. This adjustment is automatic on calculators. [Pg.53]

Expressing exponential numbers can be cumbersome and difficult to compare to each other. Chemists, therefore, instead use an acidity scale that was invented by a chemist in a bottling factory whose job it was to keep track of the acidity of the beverages being bottled in the factory. The symbol pH is derived from H for H+ ions and p for the power of 10 in the molarity of the H+ ion. Because the exponents are usually negative numbers, the sign is changed. Thus, the pH of a solution is defined as pH = - log [H+]. [Pg.99]

An exponent indicates that how many times a number is multiplied by itself. In dcimal system, exponential numbers are expressed with powers of 10 e.g.. [Pg.332]

When exponential numbers are added or subtracted, powers of 10 must be same ... [Pg.333]

This chapter has discussed some of the factors that may affect equipment reliability and necessitate data adjustment. At this time, little documented assistance is available to help develop these data adjustments. It may be necessary to get help from experts in some situations. Lastly, failure rates are often reported to several decimal places, a precision frequently unwarranted by the data. It is suggested that only the failure rate s first significant number and associated exponential power be used. [Pg.16]
