Roots, exponential notation

When a root is taken of a number expressed in exponential notation, the root of the initial number is taken and the exponent of 10 is divided by the number representing the root ... 

Extraction of the Root of a Number Written in Exponential Notation... 

Powers and Roots When numbers expressed in exponential notation are raised to a power, the exponents are multiplied by the power. When the roots of numbers expressed in exponential notation are taken, the exponents are divided by the root. 

Every chemistry student uses a calculator to solve chemistry problems. A suitable calculator can (1) add, subtract, multiply, and divide (2) perform these operations in exponential notation (3) work with logarithms and (4) raise any base to a power. Calculators that can perform these operations usually have other capabilities, too, such as finding squares and square roots, carrying out trigonometric functions, and offering shortcuts for pi and percentage, enclosures, statistical features, and different levels of storage and recall. 

Since not all electronic calculators are alike, detailed instructions cannot be given here. Read your instruction manual. You should purchase a calculator which, in addition to , —, x, and a functions, provides at least the following scientific notation (powers of ten) logarithms and antilogarithins (inverse logarithms) both natural and common (base ten) and exponentials (y ). If it has these functions, it will probably have reciprocals (1/jt), squares, square roots, and trigonometric functions as well.
