Can you solve this Amazing poem ( number theory from Ramanujan )

Show when x = ∞, then

[(x+a-b)!(8x+2b)!(9x+a+b )!] / [(3x+a-c )!(3x+a-b+c)!(12x+3b)!] = √(2/3)

explain please ?

X will always equal infinity.
It means that no matter what you choose to be the variables for a, b, and c, the answer will always be the the square root of 2/3.
