    I need it to solve a problem......is it like this? n= (p(1-p)*2^2)/(ME^2)

    Is the given formula\[ME=2 \sqrt{\frac{ P(1-P) }{ n }}\]

    And is your answer\[n=\frac{ 4P(1-P) }{ ME^2 }\]

    well, I did it like this n= (p(1-p)*2^2)/(ME^2 )

    Right, but I'm having a hard time deciphering the brackets. Knowing that \(2^2=4\), is my last post the same as your answer?
