15 i need to know the answer within 2 !

given that a­­^b = x, evaluate the following:

a^(b+2)

Work Shown:

a^(b+2) = a^b*a^2 ... break up the exponent

a^(b+2) = x*a^2 ... replace a^b with x

We don't know the value of 'a' nor the value of x, so we cannot evaluate further. This is the same as a^2*x because order of multiplication does not matter. For example, 2*3 = 6 and 3*2 = 6, so 2*3 = 3*2.

16.9 times 2.85
