Math equation enquiry

(150!) / (1!(150-1)!, since the n is large, i can just let it be 150?
As it's a big number and calculator cant be used.
Please advise how should i calculate it?

Your equation has some typos in it. Please review and repost the correct version. An answer based on what we assume you mean may be misleading and cause further confusion.

Assuming it reduces to 150!/149! then the answer is pretty obvious.

Simple division of series

(150!) / (1!(150-1)! = (150!)/(1(150-1)! = (150!)/(150-1)! = 150!/149!=

(150*149*148*...*1)/(149*148*...*1) = 150*(149*148*...*1)/(149*148*...*1)=

150*1/1 = 150

(150!) / (1!(150-1)!), since the n is large, i can just let it be 150?
As understand 150! when using calculator, there is error. May i know if there is any shortcut way of doing?
And how about when it is (150!) / (2!(150-2)!) or (150!) / 3!(150-3)!). Please advise. Thanks.

(150!) / (3!(150-3)!) = (150!/147!)/3! = (150*149*148)/6

Can you see how that works?

Mike.
BTW, you are still typing some equations wrong. I.E. (150!) / 3!(150-3)!)
