    3√2 means 3 times the square root of 2 x√3 means x times the square root of 3

    √ means square root, so √2 means the square root of 2 3√2 means 3 times the square root of 2

    Maybe the pythagorean theorem? Im confused with that too. My tutor gave the the two triangles and it looks like this:

    oh, in that case, let's look at the left triangle first

    this is a special triangle called a 30-60-90 triangle. the "x" on the bottom represents the length of the side across from the 30 degree angle. the x√3 on the left side means that side is x times √3, and the 2x on the hypotenuse means that the hypotenuse is 2 times the side x

    x can be anything

    so, for example, if the side across from the 30 degree angle is 2, then the side across from the 60 degree angle is 2√3 and the hypotenuse is 4

    so 2√3 is the simplest form for that sides value?

    meaning it wont be just a number, right? itll always be something √3

    well yea, in this case, but not always

    if x = √2 then x√3 = √2√3 = √6

    it really depends on what x is

    ok, but if x is an integer it will be √3, only if its another radical it can be simplified

    ok, im almost gwtting this but how would you use this in a problem, like how do you multiply or add x√y?

    what do you mean? if it's something like 2√3 you just leave it the way it is
