How do I transform this into simple radical form... I have no idea how to do this could you please tell me the logic behind how you do this and step by step thanks

(5^(1/2)-3^(1/2))^2

thanks again

Also can you tell me how to transform this one into radical form also

18^(1/2)-3(50)^(1/2)+5(80)^(1/2)-2(125)^(1/2)

  • Math -

    on the first, FOIL it.

    on the second
    18=9*2
    50=25*2
    80=16*5
    125=25*5
    Notice I factored out the squares, this will leave you with two terms, sqrt2, and sqrt5 terms.
