8.03x10^-8x4..82x10^12

1 answer

To multiply the two numbers in scientific notation, you can follow these steps:

  1. Multiply the coefficients: \( 8.03 \times 4.82 \)
  2. Add the exponents: \( 10^{-8} \times 10^{12} \)

Let's calculate it step by step:

  1. Coefficients: \[ 8.03 \times 4.82 \approx 38.6856 \]

  2. Exponents: \[ 10^{-8} \times 10^{12} = 10^{-8 + 12} = 10^{4} \]

Now combine the results: \[ 38.6856 \times 10^{4} \]

In proper scientific notation, you want the coefficient to be between 1 and 10. So, we can rewrite \( 38.6856 \) as \( 3.86856 \times 10^{1} \). Thus, we have: \[ 3.86856 \times 10^{1} \times 10^{4} = 3.86856 \times 10^{5} \]

Therefore, the final result is approximately: \[ 3.87 \times 10^{5} \quad (\text{rounded to three significant figures}) \]
