I am helping an adult student upgrade in Math 10. Her job is in an isolated area so we communicate through email.

I cannot find the symbol for square root and it is really annoying having to type for example: “the square root of 48” = “the square root of 16” x “the square root of 3” = “four square root 3.”

Rather than use a square root symbol I find it easier to use the power of notation: 9^(1/2) = 3 It lends itself easily to doing cubic roots and so on for example 27^(1/3) = 3.
