D sqrt((x)/(y)-4),(1)/(x)+(1)/(y)=(1)/(xy)

Convert the following equations into simultaneous equations and solve: sqrt((x)/(y))=4,(1)/(x)+(1)/(y)=(1)/(xy)

(xy)/(x-y)=(1)/(2);(xy)/(x+y)=(1)/(5) wherex +y!=0;x-y!=0

The value of f(x,y)=((4sqrt(x^(3)y)-4sqrt(x^(3)))/(sqrt(y)-sqrt(x))+(1+sqrt(xy))/(4sqrt(xy)))^(-2)(1+2sqrt((y)/(x))+(y)/(x))^((1)/(2)) when x=9,y=0.04

Convert the following equations into simultaneous equations and solve: sqrt(x/y)=4,1/x+1/y=1/(xy) .

The value of f(x,y)=((x^(3)y)^((1)/(4))-(y^(3)x)^((1)/(4)))/(sqrt(y)-sqrt(x))+(1+sqrt(xy))/((xy)^((1)/(4)))xx((1+2sqrt((y)/(x))+(y)/(x))^(4) when x=9 and y=0.04

x+sqrt(xy)+y=1

If x = 2 + sqrt3, y = 2 - sqrt3 , then find the simpliest value of (a) x - (1)/(x) , (b) y^(2) + (1)/(y^(2)) , (c) x^(3) - (1)/(x^(3)) , (d) xy + (1)/(xy)

If sqrt(y)=4x, then (x^(2))/(y) is (a) 2 (b) (1)/(16) (c) (1)/(4) (d) 4

When simplified (x^(-1)+y^(-1))^(1-) is equal to xy( b) x+y( c) (xy)/(x+y) (d) (x+y)/(xy)

If y=(log)_(e)((x)/(a+bx))^(x), then x^(3)y_(2)=(xy_(1)-y)^(2)(b)(1+y)^(2)(c)((y-xy_(1))/(y_(1)))^(2) (d) none of these
