Find the value of `x^3-y^3` if `x-y=4` and `xy=21`

Find the value of : 27x^3-y^3 if 3x-y=8 and xy=3 .

Find the value of : x^3+y^3/8 if x+y/2=9 and xy=4 .

If x - y = 4 and xy = 45, then the value of x^3-y^3 is : यदि x - y = 4 तथा xy = 45 है, तो x^3-y^3 का मान होगा :

Find the value of x^(3)+y^(3)-12xy+64, when x+y=-4

If x-y= -1 , then find the value of x^3 - y^3 +3xy

If x-y =4 and xy=45 , then the value of (x^3 - y^3) is :

If x - y = 1 , then the value of x^3 - y^3 - 3xy will be :

Find the value of x:y, if (8x-10y)/(3x+4y) = (4)/(5) .
