[00:00:00] We are doing a review in calculus and I can't solve this one problem. X^3/2 = 64

Christopher B (Tutor)
[00:00:20] Hello. I see the problem above. Do you have any thoughts on how to solve it?
[00:02:03] Actually, it's much easier than that.

Guest (Customer)
[00:02:08] good

Christopher B (Tutor)
[00:02:19] We do not need to use logs, we just need to remember our laws of exponents.
[00:03:09] Any thoughts on how we can use those laws to help with this problem?

Guest (Customer)
[00:03:15] not really

Christopher B (Tutor)
[00:03:23] That's fine.
[00:03:48] So we know that we want the solution to look something like x=(insert answer here) correct?

Guest (Customer)
[00:04:03] yes
[00:04:11] oh

Christopher B (Tutor)
[00:04:25] Sort of.
[00:05:04] I see what you mean by use the radical.
[00:05:08] Yes that is how we could do it.
[00:05:17] We could also use fractional exponents as well.
[00:05:28] Which would look like this:
[00:05:55] Does that look familiar?
[00:06:07] Yes exactly the powers will reduce to 1 on the left.
[00:06:12] So what does x equal?
[00:06:41] Perfect.
[00:06:58] Do you have any questions about what we did?

Guest (Customer)
[00:07:01] Im just making stuff to difficult

Christopher B (Tutor)
[00:07:19] It happens to all of us. I do that quite a bit when I do math as well.

Guest (Customer)
[00:07:20] thank you so much, that is all I have.

Christopher B (Tutor)
[00:07:24] Great.
[00:07:37] Please fill out the survey afterwards. I am going to end the session now. Have a good day.
