Simplify each expression, if possible. All variables represent positive real numbers. $$ \sqrt{80 c} $$
Added by Milagros V.
Step 1
In this case, 80 can be factored as $2^4 \cdot 5$, and $2^4$ is the largest perfect square. So we can write: $$ \sqrt{80 c} = \sqrt{2^4 \cdot 5 \cdot c} = \sqrt{2^4} \cdot \sqrt{5} \cdot \sqrt{c} = 4\sqrt{5c} $$ Show more…
