zero .........

we have 2^x = 1/2^y 2^x * 2^y =1 2^(x+y) =2^0 on comparing both sides, we get, x+y=0

x, y, z and k are four non zero positive integers satisfying 1/x + y/2 = z/3 + 4/k, minimum integral value of k for integral value of x, y and z will be

If 2^x = 3^y = 6 then which of the following statements is true?

1) x - y = xy 2) y - x = xy 3) x + y = xy 4) xy = x/y

If x^4 + 5y = 6 x^2 y^2 + 5x = 6 Then x,y=??
