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