Mar 19, 2013 at 13:01 comment added Mhenni Benghorbal @Xentius: It is the gamma function $\Gamma(n)=(n-1)!.$
Mar 19, 2013 at 7:53 comment added Amadeus @Xentius it's called gamma function.
Mar 19, 2013 at 7:50 comment added Xentius @MhenniBenghorbal Could you please explain me the meaning of that symbol looks like a sickle?
Mar 19, 2013 at 1:05 comment added Mhenni Benghorbal $$ 1.2.5 \ldots (3j-4)= {\frac {{3}^{j-1}\Gamma \left( j-1/3 \right) }{\Gamma \left( 2 /3 \right) }}.$$

Mar 18, 2013 at 23:40 comment added Américo Tavares This has nothing to do with your main question but there is a typo in the numerator: $-1^{j+1}$ instead of $(-1)^{j+1}$.
Mar 18, 2013 at 23:34 comment added Xentius @GerryMyerson But the person who asked me this question told me that he saw this on a book as an exercise problem. So I guess there must be a decent expression?
Mar 18, 2013 at 23:31 comment added Gerry Myerson If there isn't a solution, there isn't a problem. Not every complex mathematical expression has a simpler form. I think you have to live with what you have.
Mar 18, 2013 at 23:29 comment added Xentius @GerryMyerson while solving for $\sqrt{1+x}$, there was 1*3*5*7*..*(2j-3) at the nominator, then I multiplied both the nominator and the demoniator with 2*4*6*...*(2j-2) and found the answer. However in this case (cube root), it seems not to be working (multiplying nominator and dominator with 3*4*6*7*9*11*...). So I thought maybe there can be a way to write 2*5*...*(3j-4) in another way. But you are right, I am not sure about what to do in order to solve this problem. Do you have an idea?

Mar 18, 2013 at 23:23 comment added Gerry Myerson I don't think you can write anything for $(2)(5)\cdots(3j-4)$. Why do you feel you need to?

Mar 18, 2013 at 23:02 comment added Git Gud I slightly improved the $\LaTeX$ in your question. Please check that I kept the meaning of the question.
