" The value of "(sqrt(80)-sqrt(112))/(sqrt(45)-sqrt(63))" is : "

the value of (sqrt80 - sqrt112)/(sqrt45 - sqrt63) is :

What is the value (sqrt(5)-sqrt(3))/(sqrt(5) + sqrt(3)) - (sqrt(5) + sqrt(3))/(sqrt(5) - sqrt(3)) ?

If sqrt(5)=2.236 and sqrt(10)=3.162 , then the value of (15)/(sqrt(10)+sqrt(20)+sqrt(40)-sqrt(5)-sqrt(80)) is

sqrt(45)-3sqrt(20)+4sqrt(5)

Find the value of (sqrt(sqrt(5)+sqrt(2))+sqrt(sqrt(5)-sqrt(2)))/(sqrt(sqrt(5)+sqrt(3)))
