Of course your teacher knows the answer, she probably just didn't want to give the answer to you.
All you're doing is multiplying.
Multiply the coefficents (2*5)
Add the exponents on the corresponding variables.
The b^2 will not change, but you need to add the exponents on the a's
You can't just insert plus or minus signs when there is none there.

This is an algebraic expression, not an equation.
Multiply monomials:
(2a² b²)(5a) = 10a³ b².
