Often people see a decimal with a few numbers after the decimal point and assume it's pretty exact. In fact, we can be more exact by leaving answers with roots in them. "Simple radical form" is almost always the preferred method for a final answer because if you leave a rounded decimal, the process of rounding makes the decimal less precise. Here we do examples of simple radical form as well as the order of operations for finding a decimal approximation on your calculator.
