Radicals

= = =__**√a*√b**__= = =√(a*b)= = =

=**√a/√b**= = =__√(a/b)____=

What do you do with the coefficient of the radical?

You simply add them together. EXAMPLE: 2√2 plus 2√2 equals 4√2.

Reason: The coefficient of a radical is the same as the coefficient of x. 3x is literally 3 xs put together in a simpler form. This idea is similar to radical.

EXAMPLE: 2√2 is literally √2 plus √2. So 2√2 plus 2√2 is literally √2 plus √2 plus √2 plus √2, which is combined into 4√2. //(Could you make an example which doesn't involve so many 2's? Maybe 5√2 or something//)
