Question 79352: I cant figure out how to enter the square root symbol into this program?
But the question reads:
2 sq. root of x + 3 sq. root of y divided by sq. root of x - 4 sq. root of y.
I am supposed to simplify this one. Please help me

You can put this solution on YOUR website!
2 sq. root of x + 3 sq. root of y divided by sq. root of x - 4 sq. root of y.
--------
[2sqrtx + 3sqrty] / [sqrtx - 4sqrty]
Multiply numerator and denominator by [sqrtx + 4sqrty] to get:
= [(2sqrtx+3sqrty)(sqrtx+4sqrty)]/[x-16y]
= [2x+12y+11sqrt(xy)]/[x-16y]
