Answer 2

7 × -2

-7 × 2 × 2

1/ 7.2.2

1/7.7

Answer 3

Not clear ...
Which one is power or ...???
x or * ???

Answer 4

if it is \( 7^{-2} \) you can write that as 7^(-2) with an uparrow ^ to show (-2) is an exponent

the -2 means that you "flip" the 7:
\[ \frac{1}{7^2} \]
7^2 means 7*7

so the answer is \[ \frac{1}{49} \]
