Question

Rewrite using the properties of exponents. x^-3 A) -x3 B) -3x C) 1 x3 D) 3 x3

Answer 1

In x^-3  which would be clearer if written as x^(-3), the exponent of x is -3.

x^(-b) = 1/x^b (put the base, x, into the denominator and change the sign of the exponent).

Thus, x^(-3) = 1 / x^3     (one over the 3rd power of x).
