[00:00:02] Hi! :) i am working on exponents and products of like bases. The ws that I am doing gives expressioons containing exponents that I need to simplify and I need help!!

Erin D (Tutor)
[00:00:06] Hi there!
[00:00:21] Welcome to Tutor.com ! Let's get started.

Asha/Khalif (Customer)
[00:00:26] hello!

Erin D (Tutor)
[00:00:36] Hope your day is going great!

Asha/Khalif (Customer)
[00:00:47] thanks!

Erin D (Tutor)
[00:01:20] You're welcome.
[00:01:28] So do you have any examples to work with today?

Asha/Khalif (Customer)
[00:01:38] yes

Erin D (Tutor)
[00:02:00] Excellent.
[00:03:31] So..
[00:03:38] any idea where to go from here?

Asha/Khalif (Customer)
[00:04:00] hmmm.

Erin D (Tutor)
[00:04:19] No worries.
[00:04:26] We'll work through it together.
[00:04:44] So find all the same letters..
[00:04:59] and add the numbers (exponents) together.
[00:05:03] For example...
[00:05:31] X^2.X^4
[00:05:34] is X^6

Asha/Khalif (Customer)
[00:05:42] ohhh

Erin D (Tutor)
[00:05:43] because you add the exponents
[00:05:46] 2 and 4

Asha/Khalif (Customer)
[00:06:04] so would it be x^9?

Erin D (Tutor)
[00:06:22] Yes!!
[00:06:26] Now do the Y's

Asha/Khalif (Customer)
[00:06:43] y^5

Erin D (Tutor)
[00:06:54] You've got it!
[00:07:01] and just multiply the numbers together.
[00:07:05] combine everything
[00:07:08] and you're done :)

Asha/Khalif (Customer)
[00:08:09] ohh so it would be 12 times x^9 times y^5

Erin D (Tutor)
[00:08:26] Perfect
[00:08:36] Nice job!
[00:08:46] so 12X^9Y^5

Asha/Khalif (Customer)
[00:08:46] :)

Erin D (Tutor)
[00:08:58] :)

Asha/Khalif (Customer)
[00:09:09] can we do another one?

Erin D (Tutor)
[00:09:20] Of course!!
[00:11:14] Will you be writing it on the board?

Asha/Khalif (Customer)
[00:11:25] -2x^2y^4 times -3xy^4
[00:11:31] do u want me to?

Erin D (Tutor)
[00:11:50] If you want.
[00:11:57] Or you can just try and solve.
[00:12:00] Remember..
[00:12:04] if you have just X
[00:12:06] or just Y
[00:12:10] it's really like
[00:12:11] X^1
[00:12:14] or Y^1

Asha/Khalif (Customer)
[00:12:24] okay

Erin D (Tutor)
[00:14:36] Would you like to try and answer?

Asha/Khalif (Customer)
[00:14:46] sure!
[00:15:31] x^3y^8(-6)

Erin D (Tutor)
[00:15:48] Awesome!!
[00:15:55] Now I would put -6 up front
[00:16:01] "conventional"

Asha/Khalif (Customer)
[00:16:16] okay

Erin D (Tutor)
[00:16:28] Nice job!!!

Asha/Khalif (Customer)
[00:16:42] i think its making sense now

Erin D (Tutor)
[00:16:56] Yay!!
[00:17:04] It really appears like you're getting it!

Asha/Khalif (Customer)
[00:17:12] :)
[00:17:21] i have a question thouh
[00:17:26] *though

Erin D (Tutor)
[00:17:30] Sure!!

Asha/Khalif (Customer)
[00:18:51] my teacher taught me that if there is an expression with like bases, you keep the same base and just add the exponents (4^2. 4^3

Erin D (Tutor)
[00:19:06] Correct
[00:19:10] so X's
[00:19:13] Y's
[00:19:16] and even 4's
[00:19:22] we add the exponents
[00:19:26] of like bases..
[00:19:33] just like you've been doing with the letters.

Asha/Khalif (Customer)
[00:19:51] ohhhh okay!

Erin D (Tutor)
[00:20:10] I love watching it come together with you.. you really are getting it!
