//<span style="font-size: 12pt; color: rgb(0,128,128); font-family: Arial,Helvetica,sans-serif;">Opposite of powers, the root of the equation is a number that is multiplied by itself. //

===Example: Betty has two dollars. She is going to the store to get gum for $1.50. If she plans to use the change to buy candy that is $.10 per piece, how many pieces of candy can she buy after purchasing gum?===
