Answer:

с 60,800,000

Explanation:

Any scientific or graphing calculator can evaluate this expression for you.

__

When adding numbers in scientific notation, they need to have the same multiplier exponent. Here, it is convenient to use 10^6:

8.0×10^5 = 0.8×10^6

6.0×10^7 = 60×10^6

Then the sum is ...

(0.8 +60)×10^6 = 60.8×10^6 = 60,800,000

Come Question 14 8.0 x105 +6.0 x107 = A 14,000,000,000,000 B 140,000,000 с 60,800,000 D-example-1
