Concept:BASIC uses one-line keyboard symbols: `*` for multiplication, `/` for division, and `^` for exponentiation.Explanation:The given expression is $P\left(1+\frac{R}{100}\right)^N$.In BASIC, write $\frac{R}{100}$ as `R / 100`.Use `*` instead of the multiplication sign between $P$ and the bracket.Use `^N` to show the power $N$ applied to $\left(1+\frac{R}{100}\right)$.Therefore, the BASIC expression is written on one line as`P * (1 + R / 100) ^ N`.Answer:`P * (1 + R / 100) ^ N` — Option D.
