Question

Practice 7-2 Multiplying and dividing Radical expressions
Please do 3,10,12,19,20,21,24,27

Answer 1

on 3) multiply 50 x 15 = 750, then you have
sqrt 750x^2y^3z^6

Answer 2

I meant cubic root

Answer 3

then you find what you can multiply 3 times since it is cubic root
cubi root (5.5.5.6.x^2.y.y.y.z^2.z^2.z^2)

Answer 4

take out 5yz^2 and inside stays 6x^2

Answer 5

Practice 7-2 Multiplying and dividing Radical expressions
Please do 10,12,19,20,21,24,27

Answer 6

do you know how to do 21, that is not difficult?

Answer 7

and what about 19

Answer 8

lol i barely know how to do any of them

Answer 9

Ok, 19) you have sqrt 36x^3, you know that 36 is a perfect square because 6 x 6 = 36
therefore you have sqrt 6.6.x.x.x, which one are on pairs?

Answer 10

I honestly don't know my teacher barely taught this

Answer 11

well you see that there are 2 (6) and 2 (x), you can take out 6x and you have to live inside the x that is not with a pair, getting the answer of 6xsqrtx
now try doing 21
