The value of `(x^a.y^(-b))^5(x^5.y^2)` is

If (x)/(y) = (6)/(5) . The value of (x^(2) + y^(2))/(x^(2) - y^(2))

If x/y = 6/5 , find the value of ( x^2 + y^2 ) / ( x^2 - y^2 )

If x= (sqrt""5) + 1 and y = (sqrt""5) -1 , then what is the value of (x^(2)//y^(2)) + (y^(2)//x^(2)) + 4[(x//y) + (y//x)]+6 ?

If x:y=2:3, find the value of (3x+2y):(2x+5y)

If y=(a+bx(3)/(2))/(x^((5)/(4))) and y'=0 at x=5, then the value of (c^(2))/(b^(2)) is

The value of (x , y) if 5^(x) + 3^(y) = 8,5^(x-1) + 3^(y-1) = 2 is :

If x=(sqrt5)+1 and y=(sqrt5)-1 , then what is the value of (x^2//y^2)+ (y^2//x^2) + 4[(x//y) + (y//x)] + 6 ?

If ax+by=6,bx-ay=2 and x^(2)+y^(2)=4, then the value of (a^(2)+b^(2)) would be:
