Question

(9i)(i^2)(4i)
Pls awnser

Answer 1

36

Explanation:

We are dealing with imaginary numbers, which works differently than a normal problem.

Let's combine (9i) and (i^2) and create a multiplication problem,

9ii^2 * 4i

Multiply the constants :

`36i^2ii`

We see 4 i's in this problem, add them all together :

`36i^4`

4 i's are equal to 1, now multiply the constant :

`36 * 1`

36
