[00:00:00] Simplify the expression. Tell which properties of exponents you used X^3*x^2*x^-4

Michael K (Tutor)
[00:00:04] hello, how are you?

Pamela (Customer)
[00:00:19] I did wrong question it is as following on the board

Michael K (Tutor)
[00:00:41] ok :)

Pamela (Customer)
[00:00:49] I am ok how are you

Michael K (Tutor)
[00:01:20] good :) alright, lets get started!

Pamela (Customer)
[00:01:35] ok

Michael K (Tutor)
[00:02:00] so, we see that when we raise an exponent to another exponent, then we just multiply the exponents, right?

Pamela (Customer)
[00:02:14] right

Michael K (Tutor)
[00:02:44] so, when we do this to the exponents, what exponents will we get for x and y? :)

Pamela (Customer)
[00:03:27] do we do also multiply the 2

Michael K (Tutor)
[00:03:51] right :) but it's exponent is a 1, correct?
[00:04:00] so 1 * -5 =?

Pamela (Customer)
[00:04:21] -5

Michael K (Tutor)
[00:04:36] right :) so 2^-5 will be equal to?

Pamela (Customer)
[00:04:51] -32

Michael K (Tutor)
[00:05:36] close :) the negative in the exponent actually inverts the number, not negates it.
[00:05:48] so, what will it be then? :)

Pamela (Customer)
[00:06:27] what do you mean

Michael K (Tutor)
[00:06:40] perfect :)
[00:06:57] is there anything else we can go over or clairfy? :)

Pamela (Customer)
[00:07:21] can we do one more

Michael K (Tutor)
[00:07:28] sure :)
[00:08:47] right :) and since y is down there and has a negative exponent, what else can we do?
[00:09:20] perfect :)
[00:09:33] is there anything else I can help with or go over?

Pamela (Customer)
[00:10:06] no not now I really appreciate this

Michael K (Tutor)
[00:10:21] alright :) well take care!
