    \[D= SQRT* 3(1450) OVER 2\]

    It's a word problem. it is a principle of radical that is over the 3h and 2 fraction. h=1450

    \[\sqrt[3]{\frac{1450}{2}}\]

    is it a square root or a cube root?

    d=sqrt* 3H over 2

    square root--the one that is longer and then splits into two smaller ones as the next step.

    3h and 2 is a fraction. sqrt goes over the both of them--just one. I get that you then break it down by placing two radicals over each den and num. lost on the next step

    \[\sqrt{\frac{3\times 1450}{2}}\]

    divide first, then take the square root

    so take the den of 2 and place it under D?

    before plugging in H=1450?

    yes you can divide first. you have \[\frac{3\times 1450}{2}=2175\]

    would I have to square both sets of numbers?

    then take the square root. \[\frac{\sqrt{a}}{\sqrt{b}}=\sqrt{\frac{a}{b}}\]

    if you are just trying to compute the square root of that number, no. just use a calculator

    rationalizing denominators means something else. for example \[\frac{1}{\sqrt{2}}=\frac{\sqrt{2}}{2}\]

    but if you just want a number you can compute inside the radical and then take the square root
