Answer :

1. When we covert 19 m to mm, the result obtained is [tex]1.9\times10^4\ mm[/tex]

2. When we convert 63 μL to dL, the result obtained is [tex]6.3\times10^{-4}\ dL[/tex]

1. We can convert 19 m to mm as illustrated below:

  • Distance (in m) = 19 m
  • Distance (in mm) =?

1 m = 1000 mm

Therefore,

19 m = 19 × 1000

19 m = [tex]1.9\times10^4\ mm[/tex]

2. We can convert convert 63 μL to dL as illustrated below:

  • Volume (in μL) = 63 μL
  • Volume (in dL) =?

1 μL = [tex]1\times10^{-5}\ dL[/tex]

Therefore,

63 μL = [tex]63\ \times\ 1\times10^{-5}[/tex]

63 μL = [tex]6.3\times10^{-4}\ dL[/tex]
