How To Convert Square Roots To Exponents Dummies In general, if a is the base that is repeated as a factor n times, then. figure 1.6.1. when the exponent is 2, we call the result a square. for example, 32 = 3 ⋅ 3 = 9. the number 3 is the base and the integer 2 is the exponent. the notation 32 can be read two ways: “three squared” or “ 3 raised to the second power.”. Base: the number being raised to a power in an exponential expression. exponent: the power the base is being raised to in an exponential expression. radical: the sign used to indicate square root: \displaystyle \sqrt {} √. square root: a number when squared gives the number under the radical.
Understanding Exponents And Square Roots Definition 8.1.16. given a real number a and a positive integer n, an “ nth root of a” is a number x such that xn = a. for example, 2 is a 6th root of 64 since 26 = 64 and −3 is a fifth root of −243 since (−3)5 = −243. the case of even roots (i.e., when n is even) closely parallels the case of square roots. The exponent, or power, tells how many times to use the base as a factor in the multiplication. in the example, 7 ⋅ 7 7 ⋅ 7 can be written as 72 7 2 (7 is the base and 2 is the exponent). the exponent 2 means there are two factors. 72 = 7 ⋅ 7 = 49 7 2 = 7 ⋅ 7 = 49. you can read 7 2 as “seven squared.”.

When you find square roots, the symbol for that operation is a radical, which looks like this: when changing from radical form to fractional exponents, remember these basic forms: the n th root of a can be written as a fractional exponent with a raised to the reciprocal of that power. when the n th root of. is taken, it’s raised to the 1 n.
