What is the missing exponent in the following equation?

e^?/e^65 = e^38

To find the missing exponent, we can start by simplifying the equation.

By using the rule of exponents that states when two exponential expressions have the same base and are divided, we can subtract the exponents:
e^(? - 65) = e^38

To have the same base, the exponents must be equal:
? - 65 = 38

Now, solve for the missing exponent:
? = 38 + 65
? = 103

Therefore, the missing exponent is 103.
