Question

The minimum recommended width of the space between 6-inch by 6-inch tiles is 2^-2 inch and the maximum recommended width is 2^-1 inch. Simplify the expressions for the minimum and maximum widths of the space between the 6-inch by 6-inch floor tiles.

I got 1/3 inch is is right?

Answer 1

x^-n = 1/x^2

So, we have 1/2^2 and 1/2^1

How can you get 1/3 for either of those?
Also, they asked for two answers, not one.
