2*x^3 + x^2 + x

Step-by-step 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

Given that a^b = x, evaluate the following:2a^3b+a^2b+a^b

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

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