    or just do it b hands solve the parentheses 8-5 = 3! \[\huge\rm \frac{ 8! }{ 5!(8-5)! }\] formula for combination n_C_r n=8 r=5 \[\frac{ 8! }{ 5!(3!) }\] 8!= 8 times 7 times 6 times 5 times 4 times 3 times 2 times 1 subtract one untill u get one

    or 8!= 8 times 7 times 6 times 5! <--now you can divide 5! \[\huge\rm \frac{ 8 \times 7 \times 6 \times\cancel{ 5!} }{\cancel{ 5!} 3! }\] now 3!= ??
