Certainly! Let's go through the process of multiplying the given numbers expressed in scientific notation step-by-step:

Given:
[tex]\[ \left(9.16 \times 10^{-3}\right)\left(5.5 \times 10^6\right) \][/tex]

1. Multiply the coefficients:
[tex]\[ 9.16 \times 5.5 = 50.38 \][/tex]

2. Multiply the powers of 10:
[tex]\[ 10^{-3} \times 10^6 = 10^{-3+6} = 10^3 \][/tex]

3. Combine the results:
[tex]\[ 50.38 \times 10^3 \][/tex]

4. Convert the result to proper scientific notation:
Scientific notation typically keeps the coefficient between 1 and 10. Therefore, we convert:
[tex]\[ 50.38 \times 10^3 \][/tex]
to
[tex]\[ 5.038 \times 10^{4} \][/tex]
This is done by moving the decimal point one place to the left and increasing the exponent by 1.

Thus, the product expressed in scientific notation is:
[tex]\[ 5.038 \times 10^4 \][/tex]

So, the correct choice from the given options is:
[tex]\[ 5.038 \times 10^4 \][/tex]
