    Lightbulb Test (LaTex Practice)

    x squared - i = 0

    x^2-i=0

    x^2=i

    x=\sqrt{i}

    x=\sqrt{\sqrt-1}

    x=\pm(\frac{1+i}{\sqrt2})

    What symbol(s) is(are) needed to make Delimiters (. . .) bigger to completely encompass fraction?

    Either you can just choose bigger ones, like \big( and \big), or \Big( and \Big), or \Big[ and \Big].
    Or you can use pairs of \left( and \right) or \left[ and \right] that will be resized automatically to the height of the expression that is contained in them, like this

    x=\pm\left(\frac{1+i}{\sqrt{2}}\right)^2
