Question

How would you simplify 2 with an exponent of -3 into a fraction?

Answer 1

The general rule to apply here is that a^(-1) = 1/(a) (the reciprocal of a).

a^(-3) can be written as 1/(a^3).

Try evaluating 2 with exponent of -3.

Answer 2

\[\large x^{-n} = \frac{ 1 }{ x^n }\]
\[\large 2^{-3} = \frac{ 1 }{ 2^3 } = \frac{ 1 }{ 8 }\]
