Best ResponseYou've already chosen the best response.1for example \[4!=4\times3\times2\times1\]\[6!=6\times5\times4\times3\times2\times1\] \[\frac{4!}{6!}=\frac{4\times3\times2\times1}{6\times5\times4\times3\times2\times1}=\frac{4!}{6\times5\times4!}=\frac1{6\times5}=\frac1{30}\]

Best ResponseYou've already chosen the best response.1\[\frac{{7!}\times8!\times3!}{5!\times{9!}}=\frac{{7\times6\times5!}\times8!\times3!}{5!\times{9\times8!}}=\frac{{7\times6\times\cancel{5!}}\times\cancel{8!}\times3!}{\cancel{5!}\times9\times\cancel{8!}}\]

Best ResponseYou've already chosen the best response.1i choose not to fully expand the factorials because it takes to much space and time, bytheway 14 isn't quite right

Best ResponseYou've already chosen the best response.0@eugeniaday if you do these on your calculator, make sure you use parentheses! 7!*8!*3!/5!*9! is NOT the same as 7!*8!*3!/(5!*9!), and your calculator can't instinctively know what you *meant* to enter.
