Zadanie I
[tex]130 \ 000 \ 000=1,3\cdot10^8\\\\0,000000075=7,5\cdot10^{-8}\\\\\text{siedemset dwa miliardy}=702 \ 000 \ 000 \ 000=7,02\cdot10^{11}[/tex]
Zadanie II
[tex]8,7\cdot10^7=8,7\cdot10 \ 000 \ 000=87 \ 000 \ 000\\\\8,39\cdot10^{-5}=8,39\cdot0,00001=0,0000839[/tex]
Zadanie III
[tex]-1\frac{1}{5}\cdot(\frac{2}{3})^2=-\frac{\not6^2}{5}\cdot\frac{4}{\not9_3}=-\frac{8}{15}\\\\(108\frac{5}{6}-111\frac{3}{4})\cdot3=(108\frac{10}{12}-111\frac{9}{12})\cdot3=-2\frac{11}{12}\cdot3=-\frac{35}{12}\cdot3=-\frac{35}{4}=-8\frac{3}{4}[/tex]
