Answer:
8[tex]\sqrt{r\\[/tex]
Step-by-step explanation:
Take the square root of each of the terms in [tex]\sqrt{64r}[/tex]
[tex]\sqrt{64}[/tex] = 8
Since we do not know the value of r, we can simply express its square root with [tex]\sqrt{r}[/tex].
Since the two terms were being multiplied, we will multiply 8 by [tex]\sqrt{r}[/tex].
= 8[tex]\sqrt{r\\[/tex]
