To find the missing exponent in the equation \( h^{450} h^? = h^{215} \), we can use the property of exponents that states when you multiply powers with the same base, you add the exponents.
Starting with the left side:
\[ h^{450} h^? = h^{450 + ?} \]
Setting this equal to the right side:
\[ h^{450 + ?} = h^{215} \]
Since the bases are the same, we can equate the exponents:
\[ 450 + ? = 215 \]
To solve for the missing exponent \( ? \), we can rearrange the equation:
\[ ? = 215 - 450 \]
Calculating this gives:
\[ ? = -235 \]
So, the missing exponent is \( -235 \).
