QuestionCalculate $\frac{(2 \times 1.8)^{5}}{4 \times 6.4}$, round to 3 sig figs, find percentage error, and express as $a \times 10^{k}$.

Studdy Solution
Now, let's write the answer to part (c) in the form $a \times10^{k}$, where $\leq a<10, k \in \mathbb{Z}$.
$$0.0745\% =7.45 \times10^{-}\%$$So, the answers are(a) The exact value is236.176. (b) The value correct to3 significant figures is236. (c) The percentage error is0.0745%. (d) The percentage error in the form $a \times10^{k}$ is $7.45 \times10^{-}\%$.
