Find the value of sqrt(20+48i)

Evaluate sqrt(20+sqrt(20+sqrt(20)))

8sqrt(5)+sqrt(20)-sqrt(125)

If x=(4sqrt(15))/(sqrt(5)+sqrt(3)) then the value of (x+sqrt(20))/(x-sqrt(20))+(x+sqrt(12))/(x-sqrt(12)) is

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
