4^(log2 n)
Assuming "log" is the natural logarithm | Use instead

Input

4^(log(2) n)

Roots

(no roots exist)

Series expansion at n=0

1 + n log(2) log(4) + 1/2 n^2 log^2(2) log^2(4) + 1/6 n^3 log^3(2) log^3(4) + 1/24 n^4 log^4(2) log^4(4) + O(n^5)
(Taylor series)

Derivative

d/dn(4^(log(2) n)) = log(2) log(4)×4^(n log(2))
