multiply the powers

anonymous · Answer

So 3^2 is 9. So you'll have 9^4.

Multiply those powers out, and see which ones match, and you'll have your answer. :) I don't know the powers of 9 off the top of my head xP

anonymous · Answer

Yup! You're welcome :)

anonymous · Answer

wait... 9^4 isn't one of the answers! 9^8 maybe? or was it 3^8?

anonymous · Answer

Oh, 9^4 is your original expression. The one in the problem?

anonymous · Answer

What's 9^4? 

Then multiply out the other powers, and see which one matches the value of 9^4. :)

anonymous · Answer

its 9 to the 4th power! wait...yeah I think it is 9 to the 4th. the original equation is (3 squared) to the fourth. so yeah, 9 to the fourth would be equivalent then. thanks :)

anonymous · Answer

No prob :)

anonymous · Answer

no....no! what am I saying, 9 to the 4th is not one of the answers! this is starting to make me mad! (3squared) to the fourth power would be equivalent to ..yeah I don't even know
