To compare the thickness of a fingernail with \(4 \times 10^{-3}\) inches, let's express both measurements in decimal form.
First, convert \(4 \times 10^{-3}\) inches:
\[
4 \times 10^{-3} = 4 \times 0.001 = 0.004 \text{ inches}
\]
Next, we know that the average thickness of a fingernail is about \(0.011\) inches.
Now, if you want to see how much thicker the fingernail is compared to \(4 \times 10^{-3}\) inches, you can subtract the two values:
\[
0.011 - 0.004 = 0.007 \text{ inches}
\]
So, the difference in thickness is \(0.007\) inches.
Therefore, the thickness of the fingernail compared to \(4 \times 10^{-3}\) inches is:
\[
\boxed{0.007}
