10.07] Trevor is tiling his bathroom floor, which has an area that is represented as 175r5 square inches. Each tile has an area of one hundred seventy five r to the fifth power, all over the square root of the quantity sixty four r to the seventeenth power. The total number of tiles used can be represented by the expression below. one hundred seventy five r to the fifth power, all over the square root of the quantity sixty four r to the seventeenth power Simplify the expression for the total number of tiles used. Show your work.

is it $\frac{125r^5}{\sqrt{64r^7}}$?

3. anonymous

For which one the 1st problem?

4. anonymous

$\frac{125r^5}{\sqrt{64r^{17}}}$

5. anonymous

$\sqrt{64r^{17}}=8r^8\sqrt{r}$

if you divide you get $\frac{125}{8r^3\sqrt{r}}$

8. anonymous

ok then $\frac{175}{8r^3\sqrt{r}}$

Good job Satellite :P .

10. anonymous

Ok, thx! How would you simplify that to get Simplify the expression for the total number of tiles used

11. anonymous
