Radicals: Square And Cube Root Calculations
Bayani Gaba-gaba
The square root undoes squaring, and the cube root undoes cubing. These radical operations let you work backwards from an area to a side length, or from a volume to an edge. But radicals also have their own elegant arithmetic, and simplifying them neatly is a skill examiners reward.
In this lesson you will calculate with square roots and cube roots, and simplify radical expressions by pulling out perfect-square factors. You will learn the product rule that makes simplifying possible, and the care needed when adding and subtracting radicals.
