3.07 × 10^6=3,070,000

Answer 2

Answers are:

3.07 × 10^4 = 30,700.

3.07 × 10^-4 = 0.000307.

3.07 × 10^-6 = 0.00000307.

3.07 × 10^6 = 3,070,000.

1) 10^4 = 10 × 10 × 10 × 10.

10^4 = 10,000.

3.07 × 10^4 = 3.07 × 10,000.

3.07 × 10^4 = 30,700.

2) 10^-4 = 1 ÷ (10 × 10 × 10 × 10).

10^-4 = 1 ÷ 10,000.

10^-4 = 0.0001.

3.07 × 10^-4 = 3.07 × 0.0001.

3.07 × 10^-4 = 0.000307.

3) 10^-6 = 1 ÷ (10 × 10 × 10 × 10 × 10 × 10).

10^-6 = 1 ÷ 1,000,000.

10^-6 = 0.000001.

3.07 × 10^-6 = 3.07 × 0.000001.

3.07 × 10^-6 = 0.00000307.

4) 10^6 = 10 × 10 × 10 × 10 × 10 × 10.

10^6 = 1,000,000.

3.07 × 10^6 = 3.07 × 1,000,000.

3.07 × 10^6 = 3,070,000.
