To solve for the missing exponent in the equation \( 6^{-4} \times 6^{?} = 6^{13} \), we can use the property of exponents that states:
\[ a^m \times a^n = a^{m+n} \]
Using this property, we can combine the left side of the equation:
\[ 6^{-4} \times 6^{?} = 6^{-4 + ?} \]
So, we can rewrite the equation as:
\[ 6^{-4 + ?} = 6^{13} \]
Since the bases are the same, we can set the exponents equal to each other:
\[ -4 + ? = 13 \]
To find \( ? \), we can solve for it:
\[ ? = 13 + 4 \] \[ ? = 17 \]
Thus, the missing value is \( ? = 17 \).
