    you are making it really hard to help you you know

    this is what you have. i'll assume you want to simplify

    6 \sqrt{7} \cdot 3 \sqrt{5} = 18 \sqrt{7}\sqrt{5} = 18 \sqrt{35}


    square root of M square root of M squared
    \sqrt{M} ( \sqrt{M})^2 = M^{1/2}M = M^{3/2} = \sqrt{M^3}

    suare root of M squared over N cubed
    \frac {(\sqrt{M})^2}{N^3} = \frac M{N^3}

    (suare root of 2-3) (sguare root of 2+3
    this is the difference of two squares (\sqrt{2} - 3)(\sqrt{2} + 3) = 2 - 9 = -7

    (suare root of 3 - square root of 5) (square root of 3 - square root of 5)
    i hope you didn't mix up the signs here

    (\sqrt{3} - \sqrt{5})(\sqrt{3} - \sqrt{5}) = (\sqrt{3} - \sqrt{5})^2 = 3 - 2\sqrt{15} + 5 = 8 - 2 \sqrt{15}

    square root of x
    what is it you want here?!

    \sqrt{x} = x^{\frac 12} ??

    to the 4th square root of 2
    again, where's the instruction?

    \sqrt[4]{2} = 2^{\frac 14}

    cubed square root of x squared y cubed
    i don't know what you mean here
