Step-by-step explanation:
when you raise an exponent to a power you multiply
Also since the terms inside the parenthesis are multiplied and not added, you don't have to worry about expanding it
![(a^2b^3)^4 = a^{2*4}b^{3*4}=a^8b^{12}](https://tex.z-dn.net/?f=%28a%5E2b%5E3%29%5E4%20%3D%20a%5E%7B2%2A4%7Db%5E%7B3%2A4%7D%3Da%5E8b%5E%7B12%7D)
