My son (he is 13 BTW), just asked me to help him with this school math task:
What is a sum of figures (digits) in the result of the simple expression below?
2^2008 * 5^2011
I've solved it with my son already, but will someone here able to solve it? Remember it's a just a homework task for 13 y.o. kids
P.S. "^" in that expression is a power sign (to raise a given number to the given power)
