When you multiply an exponent directly to a base with an exponent, you multiply the exponents together. If you have multiple bases, you multiply the exponent to each base.
For example:
![(x^3)^5=x^((3*5))=x^(15)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/c7rgv0prveumsh0dhkyf25agc3msoc8b8v.png)
or
(multiply the exponent to each base, 4 and y)
![(x^2w^3)^2=x^((2*2))w^((3*2))=x^4w^6](https://img.qammunity.org/2021/formulas/mathematics/middle-school/zl2yjq9vddcihzr8huo5rg65782g6yg3wx.png)
![(2x^4y^4)^4](https://img.qammunity.org/2021/formulas/mathematics/middle-school/q9v7nl0xikoc8vbxwvrqtlimxlh0lmnc95.png)
![2^((1*4))x^((4*4))y^((4*4))=2^4x^(16)y^(16)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/v7d6k0ak6tkbm641lh7j2r67q87b1ooy5q.png)
16x^(16)y^(16) is your answer
