Hello and have a nice week !

Im asking your help with the following exercices (tried but failed).

So the first one

Find the closed form of the double summation

S(from j=1 to n) S(from i=0 to infinity) j^5/3 (1-1/2j^1/3)^I

The second one

(a) T(n)=T(n/4)+log4_n and T(1)=0 fond the closed form .

(b) A flower can live for 2 years and reproduct once a year.Specifically it reproducts during its first year of life . Find a reprospective relation that describes the number of flowers in time n and then find a closed form if we know that in time 0 there is only one flower.

Thanks in advance !!!!
