If L= lim_(ntooo) (2xx3^(2)xx2^(3)xx3^(4)...xx2^(n-1)xx3^(n))^((1)/((n^(2)+1))) , then the value of L^(4) is _____________. (a) -1/4 (b) 1/2 (c) 1 (d) none of the above

Observe the following pattern (1xx2)+(2xx3)=(2xx3xx4)/3, (1xx2)+(2xx3)+(3xx4)=(3xx4xx5)/3, (1xx2)+(2xx3)+(3xx4)+(4xx5)=(4xx5xx6)/3 and find the value of \ (1xx2)+(2xx3)+(3xx4)+(4xx5)+(5xx6)
