Please check your book to make sure you write this problem correctly. Do you mean: 2b^2 Or, (2b)^2?
1. If you just have 2b^2...
First: you can express the term without the exponent...
= 2*b*b
2. If you have: (2b)^2...
First: express the term withouth the exponent...
(2b)(2b)
= 4b^2

Is it 2b^2 or (2b)^2?
If it's 2b^2, then it's the answer since it is not an equation and is already simplified.
If it's (2b)^2, the the answer is 4b^2.

2b² = 2 x b x b. . .The square is with the b only
(2b)² = 4 x b x b. . .The square is with the coefficeint and variable
- - - - - - - - - - -s-

Calculus ? Differentiate?
Multiply the number term with the power.
and take away 1 from the power term.
to get 4b
