เนื่องจากไม่มีใครเล่นต่อ งั้นผมเล่นต่อเองละกัน ขอแบ่งเป็นสองหน้าต่างละกัน ป้องกันโรคหัวใจวาย ^^

41-80

\(41=4!+4\times4+4/4\)
\(42=4!+4!-4-4+\sqrt{4}\)
\(43=4!+4!-4-4/4\)
\(44=4!+4!-4-4+4\)
\(45=4!+4!-4+4/4\)
\(46=4!+4!+4-4+\sqrt{4}\)
\(47=4!+4!-(4/4)^4\)
\(48=4!+4!\times(4/4)^4\)
\(49=4!+4!+(4/4)^4\)
\(50=4!+4!+(4+4)/4\)
\(51=4!+4!-(4/4)+4\)
\(52=4!+4!+(4/4)\times4\)
\(53=4!+4!+(4/4)^4\)
\(54=4!+4!+(4/\sqrt{4})+4\)
\(55=4!+4!+4+\lceil\sqrt{4\times4}\rceil\)
\(56=4!\times\sqrt{4}+(4/\sqrt{4})\times4\)
\(57=4!+4!+4+4+\lfloor\sqrt{\sqrt{4}}\rfloor\)
\(58=\sqrt{(4+4)^4}-4-\sqrt{4}\)
\(59=\sqrt{4^4}-(4/4)-4\)
\(60=\sqrt{4^4}+4-4-4\)
\(61=\sqrt{4^4}+(4/4)-4\)
\(62=\sqrt{4^4}-(4+4)/4\)
\(63=\sqrt{4^4}-(4/4)^4\)
\(64=(4+4+4+4)\times4\)
\(65=(4\times4\times4)+4/4\)
\(66=(4\times4\times4)+4/\sqrt{4}\)
\(67=(4\times4\times4)+4-\lfloor\sqrt{\sqrt{4}}\rfloor\)
\(68=(4\times4\times4)+\sqrt{4\times4}\)
\(69=4!+4!+4!-4+\lfloor\sqrt{\sqrt{4}}\rfloor\)
\(70=4!+4!+4!-4/\sqrt{4}\)
\(71=4!+4!+4!-4/4\)
\(72=4!+4!+4!-4+4\)
\(73=4!+4!+4!+4/4\)
\(74=4!+4!+4!+4/\sqrt{4}\)
\(75=4!+4!+4!+4-\lfloor\sqrt{\sqrt{4}}\rfloor\)
\(76=4!+4!+4!+\sqrt{4+4}=4!\times4-4\times4-4\)
\(77=4!+4!+4!+4+\lfloor\sqrt{\sqrt{4}}\rfloor\)
\(78=4!+4!+4!+4+\sqrt{4}\)
\(79=\lceil\sqrt{4!}\rceil\times4\times4-4/4\)
\(80=4!+4!+4!+4+4=4\times4\times4+4\times4\)
