Thread: optimal consumption problem (2 period model of consumption)

hey I understand the cobb-douglas function but im unsure how you apply the concept to the question given below:

"Solve the optimal consumption problem analytically using the following Cobb-Doublas utility function: Subscripts 1 and 2 denote present (young) and future (old) periods and and denote the weighted time preferences for these two periods respectively. "

cheers

Can you state the optimisation problem?
