Question

Trevor is tiling his bathroom floor, which has an area that is represented as 117r4 square inches. Each tile has an area of square root of the quantity 9 r to the thirteenth power . The total number of tiles used can be represented by the expression below.
one hundred seventeen r to the fourth power, all over the square root of the quantity nine r to the thirteenth power

Answer 1

Ok so to be clear, the "117r4" you have written is actually "117r^4" correct?

Answer 2

Yes

Answer 3

Ok so let's draw the bathroom floor without tiles first and label the area for a start.

Answer 4

Ok :D

Answer 5

Ok, the number of tiles is represented by the written form of this:

\[117r ^{4}/\sqrt{9r ^{13}}\]


Each tile has an area of: \[9r ^{13}\]

So since there are the number of these tiles within the expression I wrote first, we will divide the first expression by a single tile (written right above) to see how many tiles there are.

Answer 6

So 117 by 9?
