Question Find the value of $(1.67 \times 10^{-7}) \div (9.11 \times 10^{-3})$ rounded to 3 significant figures.

Studdy Solution
Finally, round the result to three significant figures. Remember that zeros to the right of the decimal point but to the left of the first non-zero digit are not considered significant.
$$0.0000183 \approx0.0000183$$The result of $\left(1.67 \times10^{-}\right) \div\left(9.11 \times10^{-3}\right)$ rounded to three significant figures is $0.0000183$.
