[00:00:00] simplify

Pek Hwa D (Tutor)

[00:00:05] Welcome to Tutor.com !
Let's get started.

[00:00:29] Hello!
Yous aid you just need this checked?

Leo (Customer)

[00:00:29] hi

[00:00:41] n

[00:00:43] no

[00:00:59] well i tryed it

[00:01:10] i got 4

Pek Hwa D (Tutor)

[00:01:43] okay let's work through this together

Leo (Customer)

[00:01:46] what did i do

Pek Hwa D (Tutor)

[00:02:03] no idea let's start with a new board

Leo (Customer)

[00:02:11] ok

Pek Hwa D (Tutor)

[00:03:54] okay first let's start by looking at this without simplifying the radical

Leo (Customer)

[00:04:03] ok

[00:04:18] ok

[00:04:29] so its 3

Pek Hwa D (Tutor)

[00:04:44] this would be two of the same radicals so what you need to do first is subtract outside numbers

[00:04:51] yes 3

Leo (Customer)

[00:04:59] ok

[00:05:06] o

Pek Hwa D (Tutor)

[00:05:19] so it looks like this now

[00:05:24] did you follow that part?

Leo (Customer)

[00:05:27] ok got it

Pek Hwa D (Tutor)

[00:05:39] now
we need to simplify the radical

Leo (Customer)

[00:05:40] is thats it

[00:05:44] ok

[00:06:10] I'm following...

[00:06:11] Slow down. I'm confused.

[00:06:12] I got it! Thanks!

Pek Hwa D (Tutor)

[00:06:16] do you know how to simplify a radical?

Leo (Customer)

[00:06:49] like 3 times 32 (1/30

Pek Hwa D (Tutor)

[00:07:04] not quite

Leo (Customer)

[00:07:07] like 3 times 32 (1/3)

[00:07:21] 32^1/3

Pek Hwa D (Tutor)

[00:07:32] I see what you are doing but I believe the answer should be in radical form?

[00:07:36] not a decimal?

[00:08:00] let me show you how to break down 32

Leo (Customer)

[00:08:02] ok

Pek Hwa D (Tutor)

[00:08:12] make a factor tree, are ou familiar with that ?

Leo (Customer)

[00:08:57] 2

Pek Hwa D (Tutor)

[00:09:06] okay do you see how I did that?

Leo (Customer)

[00:09:11] yes

Pek Hwa D (Tutor)

[00:10:04] now since the root is 3( that little 3 on the outside ) for every three 2"s you have one comes out and the rest would stay in

[00:10:54] yes, that is it!

Leo (Customer)

[00:10:58] ok

Pek Hwa D (Tutor)

[00:11:01] Were you able to follow that?

Leo (Customer)

[00:11:20] yes

Pek Hwa D (Tutor)

[00:11:31] Okay good. Glad I was able to help!!

[00:11:39] Thanks for using Tutor.com.Â Please fill out the survey as you leave so we can learn how we can better help you in the future!Â

Leo (Customer)

[00:11:58] i have a nother porblem i
need help on to

Pek Hwa D (Tutor)

[00:12:14] okay go ahead

Leo (Customer)

[00:13:13] ok

Pek Hwa D (Tutor)

[00:13:51] something is missing in this problem, no variables?

[00:14:55] are you supposed to simplify and this was your answer?

Leo (Customer)

[00:15:02] yes

[00:15:17] and yes

Pek Hwa D (Tutor)

[00:15:28] oh okay, let's start from the beginning.
Can you just write the problem down and we will start over.

[00:16:00] Please write the problem down for us.

Leo (Customer)

[00:16:45] ok

Pek Hwa D (Tutor)

[00:16:54] Thanks!
Now one rule in math is that you cannot have a radical in the denominator

[00:17:26] So we need to multiply this by the conjugate of the denominator. Are you familiar with that term?

Leo (Customer)

[00:17:59] yes

Pek Hwa D (Tutor)

[00:18:17] so what would the conjugate of this denominator be?

Leo (Customer)

[00:18:44] 6

Pek Hwa D (Tutor)

[00:19:10] Not exactly.
It would be 2 + sq root 3

Leo (Customer)

[00:19:27] ok

Pek Hwa D (Tutor)

[00:19:47] now we need to FOIL both the numerator and denominator.
Can you do that part?

Leo (Customer)

[00:20:23] first you times 5 by 2 and the
sp root of 3

Pek Hwa D (Tutor)

[00:21:01] yes keep going, good start.
Go ahead and write that on the board

Leo (Customer)

[00:21:27] ok

Pek Hwa D (Tutor)

[00:22:44] do you know what rad 2 times rad 3 is?

Leo (Customer)

[00:22:55] no

Pek Hwa D (Tutor)

[00:22:59] rad 6

Leo (Customer)

[00:22:58] Slow down. I'm confused.

[00:23:18] ok

Pek Hwa D (Tutor)

[00:23:54] good job , now do the denominator

[00:25:37] very good, can you simplify anything in the denominator?

[00:26:35] Take a look at the denominator.
Do you see anything that would cancel out?

[00:27:34] The numerator does not have any "LIKE" terms so that would stay exactly as is

[00:28:25] yes that is correct for the denominator!!

[00:28:32] So what would our answer be for this one?

[00:29:37] You got it!

[00:29:48] Very good!!
Any questions on this?

Leo (Customer)

[00:29:47] ok thanks a lot

Pek Hwa D (Tutor)

[00:29:57] glad I was able to help!

Leo (Customer)

[00:29:57] no more
