`sqrt((y^(3))/(x))times sqrt((y)/(x))=`

Show that: (x^((2)/(3))sqrt(y^(-2)))/(y^(2)sqrt(x^(-2)))times(y^(2)sqrt(x^(-2)))/(sqrt(x^((4)/(3))))=(1)/(y)

Find : sqrt( y^2-x^2) times sqrt( y^2 - x^2) =

Value of y = sqrt((a^(y/x))/(a_(x/y))) xx sqrt((a_(x/z))/(a_(y/x))) xx sqrt((a_(x/y))/(a_(x/z))) is

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

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

Evaluate : y = sqrt(x) times 1/ sqrt(x)

Show : sqrt( x^-1y) times sqrt( y^-1z ) times sqrt( z^-1x) = 1
