Question

type out the response below for the following questionsolve (4i)(8i).

Answer 1

$(4i)(8i)\text{ = -32}$

Here, we want to solve a product

Mathematically;

$\begin{gathered} i\text{ = }\sqrt[]{-1} \\ So,\text{ we have} \\ (4i)(8i)\text{ = 4}\sqrt[]{-1}\text{ }\times8\sqrt[]{-1} \\ \\ =\text{ (4}\times8)(\sqrt[]{-1}\text{ }\times\sqrt[]{-1)}\text{ = 32 }\times(-1)\text{ = -32} \end{gathered}$
