First, let's express both numbers in decimal form:
- \(4.8 \times 10^{-3} = 0.0048\)
- \(9.4 \times 10^{-6} = 0.0000094\)
Now, we can perform the subtraction:
\[ 0.0048 - 0.0000094 = 0.0047906 \]
Next, we need to convert this result back into scientific notation.
To express \(0.0047906\) in scientific notation, we write it as:
\[ 4.7906 \times 10^{-3} \]
Now we round \(4.7906\) to two decimal places:
\[ 4.79 \]
Thus, the final result in scientific notation is:
\[ \boxed{4.79 \times 10^{-3}} \]
