To find the missing exponent in the equation \(10^x = 1,000,000\), we can rewrite \(1,000,000\) in terms of powers of 10.
We know that:
\[ 1,000,000 = 10^6 \]
Thus, we can set the equation:
\[ 10^x = 10^6 \]
Since the bases are the same, we can equate the exponents:
\[ x = 6 \]
Therefore, the missing exponent is 6.
