Question

(3(n+1)!)/(5n!)

Answer 1

hint:
\[(n+1)! = (n+1) \times n!\]
does that help?

Answer 2

btw...you wouldnt happen to be in an online class would you? i noticed the random jumps in topics...

Answer 3

I think I need more help, my math class last year did not go over factorials, which is kind of dumb. And answering your other question, no I am not. My teacher gave us a packet of random math questions to do over the summer.

Answer 4

well okay...
\[\huge \frac{3(n+1)!}{5n!} \implies \frac{3(n+1) \times n!}{5n!}\]
do you see how i got that?

Answer 5

how did you get the n! ?

Answer 6

look what i wrote earlier
\[\huge (n+1)! = (n+1) \times n!\]
would you like to know why this is so?

Answer 7

yes please.

Answer 8

this just goes by the basic principle of factorials
\[\LARGE a! = a \times (a-1) \times (a-2) \times (a-3) \times \cdots \times 1\]
do you get the principle of the factorials?

Answer 9

Oh yes, yes. I understand the problem now. Thanks.

Answer 10

wonderful

Answer 11

so you know how to proceed now?

Answer 12

yes, i have to cancel out the n! and simplify what's left, right?

Answer 13

yup
