A:

Answer:8.97x10^8Step-by-step explanation:(3.9x10^2)(2.3x10^6)First multiply the 3.9 and 2.3 to get 8.97. Second, simply add the powers (2+6) to get 8. Altogether we get 8.97x10^8All you need to do is multiply the first numbers (in this case 3.9 and 2.3) and add the powers (in this case 2 and 6). Leave the 10s untouched.To check your work you can go to a graphing calculator and simply plug in this exact equation and multiply. You should get 897000000, which, when put into scientific notation equals our answer 8.97x10^8Hope this helps!
