Answer 2

couldn't understand... kindly explain a bit

Answer 3

\[\frac{8!-6!}{3!\times5!}\]\[=\frac{8!}{3!\times5!}-\frac{6!}{3!\times5}\]\[=\frac{8\times7\times6\times5!}{3!\times5!}-\frac{6\times5!}{3!\times5!}\]\[=\frac{8\times7\times6}{3!}-\frac{6}{3!}\]

Answer 4

\[=\frac{8\times7\times6}{3\times2\times1}-\frac{6}{3\times2\times1}\]\[=\frac{8\times7\times6}{6}-\frac{6}{6}\]\[=8\times7-1\]

Answer 5

Thanx... got it
