[00:00:00] evaluate the expression using a calculator round the resultto two decimals places when appropriate

Karen W (Tutor)
[00:00:06] Hello

Gabriella (Customer)
[00:00:09] hi

Karen W (Tutor)
[00:00:21] Do you have a calculator handy?

Gabriella (Customer)
[00:00:23] yes

Karen W (Tutor)
[00:00:47] alrighty.... so the problem is 1974^ 2/7

Gabriella (Customer)
[00:00:55] yes

Karen W (Tutor)
[00:01:05] ok - so what answer did you get?

Gabriella (Customer)
[00:02:01] i dont have an anwswer yet i couldnt find a number that went in to 1974

Karen W (Tutor)
[00:02:29] the problem says that you can use your calculator so all you need to do is type in 1974
[00:02:34] then the ^ button
[00:03:02] then the parenthesis ( 2 divided by 7) then close the parenthesis
[00:03:08] then hit enter

Gabriella (Customer)
[00:03:25] this will give me the answer?

Karen W (Tutor)
[00:03:56] yes it will Then you round to the nearest hundredth

Gabriella (Customer)
[00:04:05] ok

Karen W (Tutor)
[00:04:19] just let me know what you get

Gabriella (Customer)
[00:04:33] 8.74

Karen W (Tutor)
[00:04:39] good job!!!
[00:04:43] You got it!
[00:04:50] Do you have any questions about it?

Gabriella (Customer)
[00:05:21] no i understand

Karen W (Tutor)
[00:05:27] super!!!
[00:05:39] Do you have any other questions?

Gabriella (Customer)
[00:05:59] i have another kind of problem i dont know where to start

Karen W (Tutor)
[00:06:11] Let's see it

Gabriella (Customer)
[00:07:01] solve the equation tound the result to two decimal places when appropriate x^6+36=100

Karen W (Tutor)
[00:07:43] ok.. I suggest that you get the x^6 by itself

Gabriella (Customer)
[00:07:49] ok

Karen W (Tutor)
[00:08:00] tell me what you get ok?

Gabriella (Customer)
[00:08:23] how would i get it by itself

Karen W (Tutor)
[00:08:46] right now is has 36 being added to it.. how do you "get rid" of the 36?

Gabriella (Customer)
[00:09:21] would i subtract the 36 from both sides

Karen W (Tutor)
[00:09:31] yes - very good!!!
[00:09:58] so what do you get?

Gabriella (Customer)
[00:10:27] 64Enter your text or URL here and press Enter to send.

Karen W (Tutor)
[00:10:37] great!!!
[00:11:07] now... if you have x^2 you take the square root... if you have x^3 you take the cube root
[00:11:29] if you have x^4 - you need to find the 4th root ----or raise it to the (1/4)
[00:11:42] since we have x^6 what should we do?

Gabriella (Customer)
[00:12:03] find the 6th root?

Karen W (Tutor)
[00:12:07] exactly!!!!

Gabriella (Customer)
[00:12:22] i just find out what number raised to the 6 would be 64?

Karen W (Tutor)
[00:12:44] that is right... or go to the calculator and raise 64 to the 1/6

Gabriella (Customer)
[00:12:57] 2

Karen W (Tutor)
[00:13:06] You got it!
[00:13:10] good job!!!!
[00:13:19] Did you follow each of the steps?
