Raise to the Square Three Times

How is this done?

(x^2)^(2)^(2)

Let me see.

(x^2)^4 = x^8

Yes?

Let me see.

3^5 = 243

So, we now have 2^(243). I think this leads to a number that must be
expressed in scientific notation. Yes?

You say?

Re: Raise to the Square Three Times

Yes, I believe the rule is work the powers backwards like you have done.

ie not (2^3)^ 5 which yields a different answer.

Re: Raise to the Square Three Times

Yes I can.  Apologies for a lot of very short responses but there were a lot of them to get through.

1. Thanks for changing my username.

2. If questions are easy, I will post several problems.

3. If questions are harder, I will post fewer problems.
