.5 = 1/2 or 2^(-1) 4^x = 2^(2x)
hence 2x = -1 x=-1/2
4^ x= .5 4 ^ x= 5 /10 4 ^ x = 1/2 ( 2^2) ^ x=2 ^( -1) 2^(2*x)=2 ^ (-1) on camparing 2x=-1
x= -1/2
If x+y+z = 7 2x-y+z = 4 Then 11y-10x = ??
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
