Question

H28−−√ was simplified and the final answer is 87√. What was the value of H in the original question?

Answer 1

Solution

To solve this problem, we only need to equate and solve for H

$\begin{gathered} H\sqrt{28}=8\sqrt{7} \\ divide\text{ both sides by }\sqrt{28} \\ H=\frac{8\sqrt{7}}{\sqrt{28}} \\ \\ H=\frac{8\sqrt{7}}{2\sqrt{7}} \\ \\ H=4 \end{gathered}$
