I need help please :(

Answer 1

Answer:

The answer is option 1.

Step-by-step explanation:

You have to apply Indices Law :

$\frac{ {a}^{m} }{ {a}^{n} } ⇒ {a}^{m - n}$

So for this question,

$\frac{ {7}^{ - 3} }{ {7}^{ - 5} } = {7}^{ - 3 - ( - 5)} = {7}^{ - 3 + 5} = {7}^{2}$

Answer 2

Answer :

7²

$\frac{ {7}^{ - 3} }{ {7}^{ - 5} } = \\ {7}^{ - 3 - ( - 5)} = \\ {7}^{ - 3 + 5} = {?}^{2}$
