How do you multiply and simplify square roots?

In: Math and Arithmetic, Algebra [Edit categories]

Answer:

Square roots can be multiplied by multiplying the numbers under the square root. For example, sqrt(4) * sqrt(5) = sqrt(4*5) = sqrt(20).

They can then be simplified by doing the opposite, splitting them apart. sqrt(20) = sqrt(4) * sqrt(5) = 2 * sqrt(5).
