Which of the following is equivalent to the expression (i * √5)^2 * 3?

Question

i^2 * 5 * 9

-15

15

5i * 3

Answer 1

The expression (i * √5)^2 * 3 can be simplified as (i^2 * 5) * 3.

Since i^2 is equal to -1, the simplified expression becomes (-1 * 5) * 3.

Thus, (-1 * 5) * 3 is equivalent to -15.

Therefore, the correct answer is -15.
