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

3.000= 3 , 6.000= 6

3 x 10^2 = 3 x 100 = 300
6 x 10^5 = 6 x 100000 = 600000
600,000 + 300 = 600300
