Question

How do you simplify Square root 18(5 square root 2 - square root 18)?

Answer 1

$\sqrt{18} (5 \sqrt{2} - \sqrt{18} ) \\ \\ = \sqrt{18} \times 5 \sqrt{2} - \sqrt{18} \times \sqrt{18} \\ \\ = 5 \sqrt{2 \times 18} - \sqrt{18 \times 18} \\ \\ = 5 \sqrt{36} - \sqrt{36} \\ \\ = 5 \times 6 - 6 \\ \\ = 30 - 6 \\ \\ = 24$

Answer 2

Answer:

→ $\Huge{24}$

Step-by-step explanation:

$\begin{lgathered}\sqrt{18} (5 \sqrt{2} - \sqrt{18} ) \\ \\ = \sqrt{18} \times 5 \sqrt{2} - \sqrt{18} \times \sqrt{18} \\ \\ = 5 \sqrt{2 \times 18} - \sqrt{18 \times 18} \\ \\ = 5 \sqrt{36} - \sqrt{36} \\ \\ = 5 \times 6 - 6 \\ \\ = 30 - 6 \\ \\ = 24\end{lgathered}$
