The average thickness of a chicken eggshell is 0.000356 m . Write an estimate for the average thickness of a chicken eggshell as a single digit times an integer power of 10 . Show your work.

To express the average thickness of a chicken eggshell, which is 0.000356 m, as a single digit times an integer power of 10, we can rewrite it in scientific notation. First, we notice that the number can be transformed into \(3.56\) by moving the decimal point to the right three places. Thus, we have: \[ 0.000356 = 3.56 \times 10^{-4} \] In this case, to express it as a single digit times an integer power of 10, we recognize that \(3.56\) can be approximated as \(4\). Therefore, the estimated representation becomes: \[ \approx 4 \times 10^{-4} \] So the average thickness of a chicken eggshell can be estimated as \(4 \times 10^{-4}\) m.
