Question

Brian is creating a collage on a piece of cardboard that has an area of 160r^4 square centimeters. The collage is covered entirely by pieces of paper that do not overlap. Each piece has an area of √r^7 square centimeters. Use the given information to determine an expression for the total number of pieces of paper used.

Answer 1

You would do this.



It is basically division. For example, if we instead say the cardboard has an area of 50 and each piece of paper has an area of 2, we would do 50/2.
