Question
Assume that variables represent nonnegative real numbers.$\sqrt{45 x^{2}}$
Step 1
The number 45 can be factorized into 5 and 9, and 9 can be further factorized into 3 and 3. The variable $x^{2}$ can be factorized into $x$ and $x$. So, we can rewrite $\sqrt{45 x^{2}}$ as $\sqrt{5 \cdot 3 \cdot 3 \cdot x \cdot x}$. Show more…
