That would be an expression with an irrational denominator. You can correct that by multiplying both the numerator and denominator by (√x - √y), giving you a difference of squares on the bottom:
(2√x - 3√y) / (√x + √y)
= [(2√x - 3√y) (√x - √y)] / [ (√x + √y)(√x - √y)]
= (2√x - 3√y) (√x - √y) / (x - y)
And expand the numerator if so desired:
= (2x - 2√[xy] - 3√[xy] + 3y) / (x - y)
= (2x - 5√[xy] + 3y) / (x - y)

It is 2*sqrt(5).
2 root 3 over 2, so square root of 3
2 times the Square root of 3 + 4
The square root of 2 plus the square root of 2 is equal to twice the square root of 2, therefore the correct answer is: 2(√2) or √8
if you take out the word ''quantity'' your answer is 25.02725024
Square root of 2 = 1.414213562... Square root of 7 = 2.645751311... The sum is 4.059964873...

root 3 - 1 all over 2
square root of 4x is 2 times square root of x, so answer is square root of x times 3 since it is 2 square roots of x plus one of them
It is 2*sqrt(5).
2 root 3 over 2, so square root of 3
