The value of x-y^x-y when x = 2 and y = -2 is

x – y ^{x – y}

= 2 – (-2)^{(2 + 2)}

= 2 – 16 = - 14

(256)^0.16 × (256)^0.09

If 10^2y = 25, then 10^-y equals

The product of the square root of x with the cube root of x is

If 9^x⁺² = 240 + 9^x, then x =

The value of x-yx-y when x = 2 and y = -2 is
