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

  1. Multiply the coefficients: Multiply the numbers \(1.87\) and \(6.7\).

    \[ 1.87 \times 6.7 = 12.529 \]

  2. Add the exponents: Add the powers of ten \(10^{9}\) and \(10^{6}\).

    \[ 9 + 6 = 15 \]

  3. Combine the results: Now combine the coefficient with the power of ten.

    \[ 12.529 \times 10^{15} \]

  4. Convert to proper scientific notation: Scientific notation requires the coefficient to be between 1 and 10. We need to adjust \(12.529\) to be \(1.2529\) by shifting the decimal point one place to the left, which increases the exponent by 1.

    \[ 12.529 \times 10^{15} = 1.2529 \times 10^{16} \]

So, the final answer in scientific notation is:

\[ \boxed{1.2529 \times 10^{16}} \]
