Odpowiedź:
530t = 5,30*10²t = 5,3*10²*10³ = 5,3*10⁵kg
65t = 6,5*10t = 6,5*10*10³kg = 6,5*10⁴kg
b) 720kg = 7,20*10² kg = 7,2*10²*10³g = 7,2*10⁵g
c) 32m = 3,2*10m = 3,2*10*10²cm = 3,2*10*10²*10mm = 3,2*10⁴mm
d) 540km = 5,40*10²km = 5,4*10²*10³m = 5,4*10⁵m
e) 21km = 2,1*10km = 2,1*10*10³m = 2,1*10*10³*10²cm = 2,1*10⁶cm
