Order of magnitude of a measure is an estimate of the base power 10 closest to a given measure.
We have:899432
[tex]10^{5}\ \textless \ (899432)\ \textless \ 10^{6}
[/tex]
[tex]10^{5}\ \textless \ (\approx8,9*10^{5})\ \textless \ 10^{6} [/tex]
Representation in scientific notation:
[tex]N = x .10^{y} [/tex]
[tex]\boxed{N = 8,9 .10^{5}}[/tex]
