Question

Evaluate the following expression.

2^-3

Answer 1

A negative exponent means that it is on the bottom of the fraction. Since this doesn't have a coefficient, it's understood that the coefficient is 1.

In an early problem, we saw that an exponent of -1 meant 1/x. So what would an exponent of -3 translate to?

Answer 2

2^-3=1/2^3=1/8=0.125

Answer 3
