Calculate 4.8 x 10-3-9.4 x 10-6. Express the answer in scientific notation rounding to 2 decimal places. (1 point)

1 answer

First, let's express both numbers in decimal form:

  1. \(4.8 \times 10^{-3} = 0.0048\)
  2. \(9.4 \times 10^{-6} = 0.0000094\)

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:

\[ \boxed{4.79 \times 10^{-3}} \]
