AAAaannndd the bot gets it wrong yet again!

But that is not scientific notation. You want C: 1x10^8

I apologize for the error in my previous response. You are correct, the correct answer is C: 1x10^8, which is obtained as follows:

(2.5x10^4)(4x10^3) = (2.5 x 4) x 10^(4+3) = 10 x 10^7 = 1 x 10^8.
