anonymous · Answer

Trevor is tiling his bathroom floor, which has an area that is represented as 175r5 square inches. Each tile has an area of$$64r$$ . The total number of tiles used can be represented by the expression below.

$$\frac{ 175r ^{5} }{ \sqrt{64r ^{17}} }$$
Simplify the expression for the total number of tiles used. Show your work.

@ghazi can you help me?

ghazi · Answer

64= 8*8

ghazi · Answer

$$\frac{ 175 r^5 }{ 8 r^8 \sqrt{r} }=\frac{ 175  }{ 8r^3 \sqrt r }$$

ghazi · Answer

$$\sqrt{R^{17}}=\sqrt{R^{16}*R}=\sqrt{(R^{2})^8*R}=R \sqrt R$$

anonymous · Answer

@ghazi  Ummmmmm what do i do im lost

ghazi · Answer

my previous post is answer

ghazi · Answer

$$\sqrt{R^2}=R$$

anonymous · Answer

can you give me a through explanation on how to solve this?

anonymous · Answer

I"m sorry, I have NO clue...

anonymous · Answer

thats ok thanks anyways you get a medal for effort

ghazi · Answer

$$\frac{ R^5 }{ R^8 }=\frac{ 1 }{ R^{8-5} }=\frac{ 1 }{ R^3 }$$

anonymous · Answer

:) awh thanks..

ghazi · Answer

$$\sqrt{R^{16}}=(R^{16})^{1/2}= R^8$$

anonymous · Answer

Wait, is that 175r^5?

anonymous · Answer

If it is, then first you'd have to find out how many tiles that are used.
(I'm sort of winging this as I go, so if I don't really make sense, then, um.... sorry.)|dw:1356665803264:dw|
