Answer 1

`8b^5+12b^3`

Explanation:

Multiply
`4b^2` by each term inside of the parenthesis.

`4b^2*2b^3=8b^5`

Multiply 4 & 2 normally, getting 8. When multiplying numbers with exponents, you add the exponents. 2+3=5.

`4b^2*3b=12b^3`

Multiply 4 & 3 normally, getting 12. Whenever a number has a variable, the variable has an exponent of 1. So when you add the exponents, you get 2+1=3.
