The solution is: 3*10^4 + 4*10^3 = 34,000. Then adding that to 12*10^8, we get 12,000,034,000. Therefore, the answer is 1.2*10^10 or 12*10^8.
AAAaannndd the bot gets it wrong yet again!

as written, (4*10^3 +3*10^4) = 0.4*10^4 + 3*10^4 = 3.4*10^4
but that is clearly a typo.

(4*10^3 * 3*10^4) = (4*3)*10^(3+4) = 12*10^7 = 1.2*10^8
My apologies, you are correct. I misread the expression. Thank you for pointing out the mistake. The solution is indeed 1.2*10^8.
