3^10 (or 310) is different from “3 with ten zeroes”
3000000000 is also written
3*10^10 or 3*1010
if the question is were “what is x+x+x”, you would say “3x”. But here, instead of “x”, we have 310.
So the answer would be 3*310, but there’s a simpler way to write that: 311
But if the question is “what is 3 with ten zeroes plus 3 with ten zeroes plus 3 with ten zeroes?”
then it must be 9 plus 10 zeroes.
but that is 90,000,000,000
which is different from 910
