    Ok, so I have this entire section on Radicals and Simplfying them. I do not know how the hell to do half of these questions, so if someone could show me the work for the question I will give as an example I will be grateful.

    Question: 4√150
    Answer: √20√6

    If someone could show the process used for this type of question, I will give you a cookie.
    Thanks.

    On that site, I skimmed through it looking for the question type and it seems to have skipped this. It is one Simplified Radical, and I have to somehow simplify it further. However, when I do it the way I was taught the answer key provides an entirely different answer.

    the answer for the top one should be 20√6
    and the bottom one should be 2√30
    i think

    I'm pretty sure RST go it.

    Basically, find something that can be squared that is a multiple of the number.

    Example:√8

    2*2*2=8
    2[sup]2[/sup]*2=8

    b Root of a square is the base #, so √2[sup]2[/sup] = 2. The 2 is out of the thing.2√2 the answer. Note that example is easy lol. Also, when you take the number out of the root thing, you multiply it by the other outside number.

    4√150 -step 1
    4√25x6 -step 2
    4x5√6 -step 3
    20√6 -step 4

    Step 1: the problem
    Step 2: Find the biggest perfect square in the number
    Step 3: Since the perfect square is in the radical sign, take its square root and multiply it by the outside number
    Step 4: ta-dah
