Final answer:

The expression that represents the exponent in the formula A = P(1 + ?) is n * t * r.

Step-by-step explanation:

The expression that represents the exponent in the formula A = P(1 + ?) is option (d) n * t * r.

Let's break down the formula to understand each component:

A represents the amount of the investment after t years.

P represents the initial investment.

n represents the number of times the investment is compounded per year.

r represents the interest rate.

So, when you multiply n, t, and r together, you get the exponent that is used in the formula.
