ANSWER
h⁴
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,
[tex]\frac{a^b}{a^c}=a^{b-c}[/tex]
In this case, the base is h,
[tex]\frac{h^7}{h^3}=h^{7-3}=h^4[/tex]
Hence, the simplified expression is h⁴.
