How To Solve A Square Root Problem
It also has a whole list of other functions available such as in geometry, where one can easily map the area of a square to its side length.
But my steps above show how you can switch back and forth between the different formats (multiplication inside one radical, versus multiplication of two radicals) to help in the simplification process.

You don't want your handwriting to cause the reader to think you mean something other than what you'd intended.
These exercises, activities and games are designed for students to use independently or in small groups to practise number properties.
Some involve investigation (see Related Resources) and may become longer and more involved tasks with subsequent recording/reporting. These investigations are designed for students to use in small groups to practise number properties.
