15 i need to know the answer within 2 !

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

a^(b+2)

x*a^2 or a^2*x

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.

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
