Answer
a. 205,000 $\Omega$
b. 205,000 $\Omega$ and 55,000 $\Omega$
Work Step by Step
a. Since the measurement 205,000 $\Omega$ has 3 significant digits (the most), then it is the most accurate.
b. Since the precision of the measurements 205,000 $\Omega$ and 55,000 $\Omega$ is 1000, then they are the most precise measurements. The other values have a larger precision of 10,000.
