Answer :
Answer:
7²
Step-by-step explanation:
[tex]7^{-2}\\[/tex]
Write the reciprocal to make the power positive
[tex]\frac{1}{7^2}[/tex]
The multiplicative inverse of [tex]\frac{1}{7^2}\ is\ 7^2[/tex]
[tex] {7}^{2} [/tex]
Because
[tex] {7}^{ - 2} = \frac{1}{ {7}^{2} } [/tex]
If we multiply both :
[tex] {7}^{2} \times \frac{1}{ {7}^{2} } = 1[/tex]
