Answer 1

See below

Explanation:

(5.3 x 10^8) − (8.2 x 10^6).

5300 x 10^6 Move the decimal point 2 places to the right, and reduce the exponent by 2

5300 x 10^6

- 8.2 x 10^6

5291.8 x 10^6

The remaining terms do not have mathematical operators, but we'll assume they are to be subtracted.

2.9 x 10^2

- 5.218 x 10^2

- 2.222 x 10^2

2.9 x 10^8

- 5.218 x 10^8

Same as above
