Answer 1

To express numbers in scientific notation, we write them in the form of a number multiplied by a power of 10.

Step-by-step explanation:

To express numbers in scientific notation, we need to write them in the form of a number multiplied by a power of 10. Let's go through each number:

a. 6.60 × 10³: The number is already in scientific notation.

b. 8.20 × 10⁹: The number is already in scientific notation.

c. 2.0 × 10⁻²: The number is already in scientific notation.

d. 8.7 × 10⁻³: The number is already in scientific notation.

e. 0.00012: We can rewrite this as 1.2 × 10⁻⁴.

f. 3.45 × 10^−⁹: The number is already in scientific notation.
