To find the missing exponent in the expression \(10^x = 100,000\), we can express \(100,000\) in terms of powers of \(10\).
We know that: \[ 100,000 = 10^5 \]
Now, we can set up the equation: \[ 10^x = 10^5 \]
Since the bases are the same, we can equate the exponents: \[ x = 5 \]
Therefore, the missing exponent is \(5\).
