To find the missing exponent in the equation \(10^x = 10,000\), we can express 10,000 as a power of 10.
We know that: \[ 10,000 = 10^4 \]
Now we can rewrite the equation as: \[ 10^x = 10^4 \]
Since the bases are the same, we can set the exponents equal to each other: \[ x = 4 \]
Thus, the missing exponent is: \[ 4 \]
