Rewrite a^5 x a^-3 in the form a^n

The answer is A^2

Step-by-step explanation:

When you are dividing, You subtract exponents if they have the same base.

The base (variables) are the same. So you subtract the powers.

Which are 5 and -3. You subtract those two powers 5 minus negative -3 which gives you 2.  So it's  a^-2

Sorry for the long explanation I hope you understand it. And if I made it harder to understand the answer sorry oops have a good day and stay safe ;D.

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm

it is b)
