What is the answer to (12^2) ^3 times 12^-4

and 12^7 times 12^-5 over 12^2

Answer: 12² = 144

12² : 12² = 1

Step-by-step explanation:

I'll go through it backwards: 12^7 times 12^-5 You subtract the - 5 from 7 in the exponents to get 12^2. 12^2 divided by 12^2 is 1.

(12^2) ^3 works out to 12^6 because you multiply the exponents when its a power raised by a power. Then you subtract the 4 from the 6 (or add - 4 + 6) to get 12^2.

That means 12 squared, same as 12 times 12

That's 144.

If you have to multiply the two parts together, It's 144 times 1.

If "and" means "add them together"- - YOU KNOW!
