Answer
a) 84.3 millimeters
b) 2.41 meters
c) 0.00002945 cm = 2.945 $\times$ $10^{-5}$ cm
d) 14.45 km
e) 235300 millimeters
f) 0.9033 micrometers
Work Step by Step
a) 1 cm = 10 mm
Thus 8.43 cm = 8.43(10) = 84.3 mm
b) $10^{2}$cm = 1 meter
Thus 2.41 $\times$ $10^{2}$cm = 2.41 m
c) 1 nm = $10^{-7}$cm
Thus 294.5 nm = 294.5 $\times$ $10^{-7}$cm = 2.945 $\times$ $10^{-5}$cm
d) $10^{3}$m = 1 km
Thus 1.445 $\times$ $10^{4}$m = 14.45 km
e) 1 m = 1000 millimeters (mm)
Thus 235.3 m = 235300 mm
f) 1 nm = $10^{-3}$ micrometers
Thus 903.3 nm = 0.9033 micrometers
