Question

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

Answer 1

Answer:

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
