Question

What is the answer to (12^2)^3 times 12^-4 and 12^7 times 12^-5 over 12^2

Answer 1

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!
