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

Simplify the expression for the total number of tiles used. Show your work

Answer 1

117r^4?

Answer 2

first, try obtaining the square root of 9 then put that outside of the root so you are left with sqrt (r^13), which is r^6 (sqrt[r]) try to simplify from that point on

Answer 3

also, think about this, if 3 is a factor of 60, then obviously 120 is, and 117 is 3 less than 120

Answer 4

if you want a longer method 30 + 30 + 30 + 30 - 3

Answer 5

suggesting that 117 can be divided into 3
