\[\displaystyle 7\times10^{12}\times4\times\frac{10^5}{2}\times10^{-4}\]

\[\displaystyle \frac{(10^{-3})^{-2}}{\sqrt5}\times\frac{5}{0,01^{-3}}\]

\[\displaystyle \frac{(0,05)^{-2}\times(0,36)^2}{(0,15)^{-2}\times(0,18)^2}\]

\[\displaystyle \frac{(0,001)^{-4}\times10^{-6}}{10^{7}\times(1000)^{-3}}\]

\[\displaystyle \frac{10^{-4}\times(0,01)^2}{\frac{1}{100}\times(0,001)^2}\]
