" (ix) "(6x^(2)times9y^(-3))/((2x)^(-4)times(3y)^(2))

Solve : (3^(6)times y^(8))/(9^(2)times y^(3))

(x^(3))/(9y^(2))times(27y)/(x^(5)) =____.

Find the value of ( (x^-2 times y^-4 )/ ( x^-3 times y^-1) ÷ y^-2/x^-1 )

Simplify (4x^(2)y)/(2z^(2))times(6xz^(3))/(20y^(4))

The solution of the differential equation (dy)/(dx)+(x(x^(2)+3y^(2)))/(y(y^(2)+3x^(2)))=0 is (a) x^(4)+y^(4)+x^(2)y^(2)=c (b) x^(4)+y^(4)+3x^(2)y^(2)=c (c) x^(4)+y^(4)+6x^(2)y^(2)=c (d) x^(4)+y^(4)+9x^(2)y^(2)=c

Simplify (x+4)/(3x+4y) xx (9x^(2) - 16y^(2))/(2x^(2) +3x-20)

(-(7)/(5)x^(2)y)xx((3)/(2)xy^(2))xx(-(6)/(5)x^(3)y^(3))
