Question 778173: I need help on 2 questions. My first question is what is the sqrt (Square Root) of 24 x squared y to the 3rd power (√24x²y³). My second question is what is 3/4-√5 (the slash mark between 3 and 4 is a division sign). Can you add an explanation too? Thanks!!! Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! what is the sqrt (Square Root) of 24 x squared y to the 3rd power
√24x²y³ = sqrt[4x^2y^2]*sqrt[6y] = 2xy*sqrt(6y)
==============================
My second question is what is 3/(4-√5) (the slash mark between 3 and 4 is a division sign).

To rationalize the denomiinator, multiply numerator
and denominator by 4+sqrt(5)
------
= [3(4+sqrt(5)]/[(4-sqrt(5))(4+sqrt(5))
------
= [12+3sqrt(5)]/[16-5]
------
= [12+3sqrt(5)]/11
