Question

Answer true or false to each statement. If false, say why. Every pure imaginary number is a complex number.

Answer 1

True

Explanation:

True.

Every pure imaginary number is a complex number.

In mathematics, a complex number is a number of the form a + bi, where a and b are real numbers, and i is an imaginary unit with the property that i² = -1.

When a = 0, we have a pure imaginary number, bi.

So, all pure imaginary numbers are indeed complex numbers.
