Answer 2

14) Notice that:

`136.5=13.65*10.`

Therefore:

`136.5/10=(13.65*10)/10.`

Now, we know that:

`(a* b)/ b=a\text{.}`

Then:

`(13.65*10)/10=13.65.`

18) Notice that:

`8100=0.81*10^4\text{.}`

Therefore:

`\begin{gathered} 8100/10^4=(0.81*10^4)/10^4 \\ =0.81. \end{gathered}`

Answer:

`\begin{gathered} 136.5/10=13.65, \\ 8100/10^4=0.81. \end{gathered}`
