Question

B.3 Evaluate variable expressions involving integersAZTIf h = –3 and j = –5, what is j − 3h?

Answer 1

Solution

- The solution steps are given below:

$\begin{gathered} h=-3,j=-5 \\ \text{ Substitute the values of j and h into the expression given. We have:} \\ \sqrt{j-3h}=\sqrt{-5-3(-3)} \\ \\ =\sqrt{-5+9}=\sqrt{4} \\ \sqrt{4}=2 \\ \\ \therefore\sqrt{j-3h}=2 \\ \end{gathered}$

Final Answer

The answer is 2
