The expression which is equivalent to √(-9) is 3i.

<h3>What is Complex number?</h3>

A complex number is the sum of a real number and an imaginary number. A complex number is of the form a + ib and is usually represented by z.

Here, given expression;

    y = √(-9)

    y = √9 X √(-1)

   y = 3√(-1)

   y = 3i

Thus, the expression which is equivalent to √(-9) is 3i.

Simplify by dividing [ -3/-8] divided by 5/9 (5 points)
rewona [7]

Answer: D

Step-by-step explanation:

(3/8) / (5/9) is the same as multiplying (3/8) by (9/5) which is 27/40. I'm not sure if there's an error between C and D because those are both the same answer since dividing a negative number by a negative number gives you a positive number.

I think C was supposed to be -27/40 so D is the correct answer since it's positive.
