4.82 × 10¹²

3.2 X 10⁴

Multiply the numbers above. Show your work below. For example: 2.3 X 10³ 1.7 X 10³ = 4 X 10³

1 answer

To multiply the given numbers in scientific notation, follow these steps:

Given:

  • \( 4.82 \times 10^{12} \)
  • \( 3.2 \times 10^{4} \)

Step 1: Multiply the coefficients

Multiply the two decimal numbers: \[ 4.82 \times 3.2 \]

Calculating: \[ 4.82 \times 3.2 = 15.424 \]

Step 2: Add the exponents

Add the exponents of 10: \[ 10^{12} \times 10^{4} = 10^{(12 + 4)} = 10^{16} \]

Step 3: Combine the results

Now combine the results from Step 1 and Step 2: \[ 15.424 \times 10^{16} \]

Step 4: Adjust the coefficient if necessary

Since the coefficient \( 15.424 \) is greater than 10, we need to convert it to scientific notation: \[ 15.424 = 1.5424 \times 10^{1} \]

So: \[ 15.424 \times 10^{16} = 1.5424 \times 10^{1} \times 10^{16} = 1.5424 \times 10^{(1 + 16)} = 1.5424 \times 10^{17} \]

Final Answer

Thus, the final answer for the multiplication of the two numbers is: \[ 4.82 \times 10^{12} \times 3.2 \times 10^{4} = 1.5424 \times 10^{17} \]
