How do you rewrite ${(- 7)}^{- 1}$ without the exponent?

Open in App

Solution

Rewrite the expression:
The exponent rule of real number states that $a^{- b} = \frac{1}{a^{b}}$ .
So we can write the given expression as ${(- 7)}^{- 1} = \frac{1}{{(- 7)}^{1}}$ .
Since power $1$ gives the same number we can further write it as :
$\frac{1}{- 7}$
Hence, $\frac{1}{- 7}$ is the required result.
