To solve the equation \( \frac{x^6}{x^?} = x^4 \), we can use the properties of exponents.
Recall that when dividing like bases, we subtract the exponents:
\[ \frac{x^a}{x^b} = x^{a-b} \]
Applying this to our equation:
\[ \frac{x^6}{x^?} = x^{6-?} \]
So we can rewrite the equation as:
\[ x^{6-?} = x^4 \]
Since the bases are the same, we can set the exponents equal to each other:
\[ 6 - ? = 4 \]
Now, solve for \( ? \):
\[ 6 - 4 = ? \] \[ ? = 2 \]
Thus, the value of \( ? \) is \( \boxed{2} \).
