Answer 1

[AI-generated answer — Bot GPT 3.5]

4.8 × 10-3 = 0.0048

9.4 x 10-6 = 0.0000094

Both of these answers are already in scientific notation. Rounding to 2 decimal places, the answers are:
4.8 × 10-3 = 0.00
9.4 x 10-6 = 0.00

Answer 2

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

To multiply two numbers in scientific notation, you need to multiply the two coefficients and add the exponents of the respective powers of 10.

Let's calculate:

4.8 × 10^(-3) × 9.4 × 10^(-6)

Multiplying the coefficients: 4.8 × 9.4 = 45.12

Adding the exponents: -3 + (-6) = -9

So, the result is 45.12 × 10^(-9).

To express the answer in scientific notation, we need to write it in the form A × 10^B, where A is the coefficient and B is the exponent.

Rounded to 2 decimal places, the answer is 45.12 × 10^(-9).

Answer 3

To calculate the product of two numbers written in scientific notation, we multiply the coefficients and add the exponents.

1. First, let's calculate the product of the coefficients:
4.8 x 9.4 = 44.16

2. Next, let's add the exponents:
10^(-3) x 10^(-6) = 10^(-3 + -6) = 10^(-9)

3. Now we have the product in scientific notation as:
44.16 x 10^(-9)

4. To express the answer in scientific notation rounded to 2 decimal places, we need to adjust the coefficient:
44.16 rounded to 2 decimal places is 44.16.

Thus, the final answer in scientific notation rounded to 2 decimal places is:
44.16 x 10^(-9)
