Integer ordered pairTotal number of integer ordered pair $\displaystyle (m,n)$ in $\displaystyle \displaystyle \binom{m}{n} = 120$ |

Clarify question. Integer ordered pair? |

5! = 120. I'm assuming "integer ordered pair" just means that m and n must be integers, which is normally all we deal with when working with permutations and combinations. |

So we get two positive integer ordered pair $\displaystyle (m,n) = (120,1),(120,119)$ But I did not understand how can i calculate other Positive integer ordered pair Thanks |
