In order to simplify square roots with variables that are to be multiplied, treat the variables as factors. Once the radicands are factored completely, cancel any like terms and multiply the simplified square roots. More »

The basic rule in adding and subtracting variables with exponents is they must be like terms. Like terms consist of the same variable or set of variables raised to the same power. The numerical coefficients of these term... More »
