4√(5*x^8*y^3)/(27*x^2)

Need to simplify and rationalize the denominator.

Just a little confused where to start, i already seperated the top and bottom of the brackets and each individual thing inside. And the first *4√* being "fourth root"

Alright that makes tons of sense. I just havent done any of this math in a long while and im a whole lot rusty.

Only thing that im stuck on is that its supossed to be X/3 4√15*x^2*y^3

I get where i get the x/3 from, but the x^2 under the 4th root i do not. And i get where the 4th root comes from. - September 11th 2009, 10:54 PMGrandad
