Hello!

(-8)^2 means -8 x (-8).

The answer to this would simply be:
-8 x (-8) = 64

Because a negative number is being multiplied by another negative number, the answer becomes a positive number. 

I hope this helps you! Have a great day!

I have a problem -3x-7=-13. When isolating x I divide x by -3 then divide -13 by -3 correct?
rosijanka [135]

Hello!

no, that is not the correct way to isolate x. you were somewhat on the right track however.

here's the correct way:

add 7 to both sides to get -3x = -6

then divide both sides by -3 to get x = 2

I hope this helps, and have a nice day!
