Question

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

2a^3b+a^2b+a^b

Answer 1

It would be 2*x^3 + x^2 + x I got this question right.

Explanation:

Answer 2

2*x^3 + x^2 + x

Explanation:

a­­^b = x

Then,

a­­^(2b) = a­­^b*a­­^b = x* x = x^2

a^(3b) = a­­^b*a­­^b*a­­^b = x*x*x = x^3

2*(a^3b) + (a^2b) + (a^b)

= 2*(x^3) + (x^2) + (x)

= 2*x^3 + x^2 + x
