- What is the sum of sum of digits of $4444^ {4444^ {4444}}$?
A recent question asked about the sum of sum of sum of digits of $4444^ {4444}$ The solution there works mainly because the number chosen is small enough for the sum of sum of sum to be equal to the repeated sum: i e if we sum digits further, the result does not change

- Write down the sum of sum of sum of digits of $4444^{4444}$
There's the fact that $4444^ {4444}$ has at most $4\cdot4444=17776$ digits (actually it has less) The sum of digits can therefore not be larger than $17776\cdot9=159984$ which has only $6$ digits, which means the sum of sum of digits cannot be larger than $6\cdot9=54$
