How do you multiply two radicals together?
If they have the same index, ie, both sqrt or both cube root, etc,
root%28n%2Ca%29%2Aroot%28n%2Cb%29+=+root%28n%2Ca%2Ab%29
==========================
I have a few problems I don't undertand
1.) square root of 185 =~ 13.6
------------------
2.)6 square root 90
= 6*sqrt(9)*sqrt(10)
= 6*3*sqrt(10)
= 18sqrt(10)
---------------------
3.)square root 10 times square root 30
= sqrt(10)*sqrt(10)*sqrt(3)
= 10sqrt(3)

Multiplying two radicals,
sqrt%282%29%2Asqrt%283%29=sqrt%282%2A3%29=sqrt%286%29

That's it in a nutshell.

1)sqrt%28185%29=sqrt%285%29%2Asqrt%2837%29
2) 6sqrt%2890%29=6sqrt%282%2A5%2A9%29=6%2A3%2Asqrt%2810%29=18sqrt%2810%29
