(n+1)=12 n! 7!-8*9 8! 13! 9!*4!

(n+1)=12 nie wiadomo o co chodzi n! = 1*2*3*4*.... (n-1)*n 7!-8*9 = 1*2*3*4*5*6*7-8*9=5040-72 = 4968 8! = 7! * 8 = 40320 13! = 8! * 9 *10 * 11 * 12 *13 = 6227020800 9!*4! = 1*2*3*4*5*6*7*8*9 * 1*2*3*4 = 8709120

(n+1)=12 n+1=12 n=12-1 n=11 11! = 1*2*3*4*5*6*7*8*9*10*11=39916800 7!-8*9=7!-72=1*2*3*4*5*6*7-72=5040-72=4968 8!=1*2*3*4*5*6*7*8=40320 13!=1*2*3*4*5*6*7*8*9*10*11*12*13=6227020800 9!*4!=(1*2*3*4*5*6*7*8*9)*(1*2*3*4)=362880*24=8709120 licze na maxa;) ! (silnia) to chyba najlepsza rzecz w matmie;) pozdrawiam: miss001
