ANSWER
h⁴
Step-by-step explanation
When we have a quotient between two powers and they both have the same base, we can simplify the expression by writing the base raised to the difference of the exponents,
![(a^b)/(a^c)=a^(b-c)](https://img.qammunity.org/2023/formulas/mathematics/college/wi4ktmqjld2plxk9bssn7eadfpb0y8v3l0.png)
In this case, the base is h,
![(h^7)/(h^3)=h^(7-3)=h^4](https://img.qammunity.org/2023/formulas/mathematics/college/bdpe8fuy98nz93mffbpxmfz9lrmeloe310.png)
Hence, the simplified expression is h⁴.
