Question

What is the order of magnitude of the number 899,432

Answer 1

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)}`

Answer 2

8.9 x 10^5

hope this helped.
