sqrt(5+2x-421)

Find x and y if: (3/sqrt(5) x-5)+i2 sqrt (5) y= sqrt(2)

lim_(x rarr 5) (sqrt(2x-3)-sqrt(3x-8))/(sqrt(2x-1)-sqrt(3x-6))= _______.

sqrt(5)x^(2)+2x-3sqrt(5)

Factorise: sqrt5 x^(2) + 2x- 3sqrt5

If x =(sqrt(5)-2)/(sqrt(5)+2) and y = (sqrt(5)+2)/(sqrt(5)-2) : find : x^(2)+ y^(2)+xy

int_(2)^(3)sqrt(2x-sqrt(5(4x-5)))+sqrt(2x+sqrt(5(4x-5)))dx Find the value of the definite integral

The value if definite integral int_(3/2)^(9/4)[sqrt(2x-sqrt(5(4x-5)))+sqrt(2x+sqrt(5(4x-5)))] dx is equal to

If x =(sqrt(5)-2)/(sqrt(5)+2) and y = (sqrt(5)+2)/(sqrt(5)-2) : find : x^(2)
