Answer 1

Do you know how to reduce radicals?

Answer 2

no

Answer 3

actually maybe I do

Answer 4

Ok try to reduce the radical \[\sqrt{4y^3}\]

Answer 5

tell me what you get

Answer 6

2y² and 2y Idk if that's right

Answer 7

Not quite...let me show you how i do it...

Answer 8

First if I have a single term under a radical I work on the Coefficient (number part) first. SO say I have \[\sqrt{72}\]

Answer 9

What I do is, I start to factor 72 using the good old fashioned factor tree. If I can factor out perpect squares I do that if I can.

Answer 10

You with me?

Answer 11

yes u an if u want or u can go with prime #s

Answer 12

Sure.. I usually do poerfect squares if I see them so I can reduce it quickly bu either way works...
