Use longer division its really easy
Expressions can be read as how many times you're multiplying a number by itself.
(1/2)^4 can be rewriten as (1/2)*(1/2)*(1/2)*(1/2), which simplifies to 1/16
By using these measurements and drawing out a triangle, you have two sides “a” and “b” and are trying to find “c”. using pythagorean theorem you can determine that “a^2 + b^2 = c^2”. plug in your distances (20 and 14) and you get 24.4 as your distance.
