(1.8 × 10^9) + (3.4 × 10^9) = 5.2 × 10^9

Answer 1

This can be calculated by simply adding the coefficients together and keeping the same base value:

(1.8 + 3.4) × 10^9 = 5.2 × 10^9

Answer 2

is there another way to put it

Answer 3

Yes, another way to put it is to add the coefficients first and then rewrite the result in scientific notation:

1.8 × 10^9 + 3.4 × 10^9 = 5.2 × 10^9
