To multiply square roots, first multiply the radicands, or the numbers underneath the radical sign. If there are any coefficients in front of the radical sign, multiply them together as well. Finally, if the new radicand can be divided out by a perfect square, factor out this perfect square and simplify it.

To multiply two square roots, we just multiply the radicands and put the product under a radical sign. Let’s follow the same steps we did before, where we rewrite the product of the square roots as the square root of the product of the radicands.
To multiply radicals, first verify that the radicals have the same index, which is the small number to the left of the top line in the radical symbol. Just keep in mind that if the radical is a square root, it doesn’t have an index.
There is a fun method for calculating a square root that gets more and more accurate each time around: a) start with a guess (let's guess 4 is the square root of 10) b) divide by the guess (10/4 = 2.5) c) add that to the guess (4 + 2.5 = 6.5) d) then divide that result by 2, in other words halve it. (6.5/2 = 3.25)
