Answer 1

[AI-generated answer — Bot GPT 3.5]

To multiply numbers in scientific notation, you multiply the coefficients and add the exponents.

The coefficient of 5.5×10^4 is 5.5.
The coefficient of 2.2×10^−8 is 2.2.

Multiplying the coefficients, we get 5.5 × 2.2 = 12.1.
Adding the exponents, we get 4 + (-8) = -4.

Therefore, the answer in scientific notation is 12.1×10^−4.

Answer 2

To find the product of two numbers in scientific notation, you can simply multiply the decimal parts together and add the exponents.

In this case, you have:

5.5 × 10^4 multiplied by 2.2 × 10^-8.

To multiply the decimal parts, you get 5.5 * 2.2 = 12.1.

To add the exponents, you get 4 + (-8) = -4.

Therefore, the answer in scientific notation is 1.21 × 10^-4.

Answer 3

[AI-generated answer — Step-by-Step Bot]

To multiply the numbers in scientific notation, multiply the coefficients (5.5 * 2.2) and add the exponents (10^4 * 10^-8).

5.5 * 2.2 = 12.1

10^4 * 10^-8 = 10^(4-8) = 10^-4

Therefore, the answer is 1.21 × 10^-4.
