    \[2(4n-3)^\frac{ 1 }{ 2 }-1=0\] How do you think you should start?

    There are 2 things to do before that. First you have to add the 1 to both sides. Then divide both sides by 2

    no. ignore the stuff in parentheses for now. All of that is under an exponent. Think of solving an equation as reverse order of operations (PEMDAS/BEDMAS). So you need to deal with the addition and subtraction first. (that's moving the 1 to the right side of the equal sign.) Then we'll do multiplication and division (that's moving the 2 to the right side of the equal sign). Then we'll do the exponent (the 1/2) An then the last steps are dealing with the 4n - 3 inside parentheses.|dw:1440866106931:dw|

    So it's -1 + 1 on the left side and 0 + 1 on the righ

    now square both sides to get rid of the exponent|dw:1440867604740:dw|
