In Canada in 1998 the estimated number of households written in standard decimal notation is 3939000
Solution:
Given that in 1998 estimated number of households that owned 2 or more vehicles was [tex]3.939 \times 10^{6}[/tex]
Need to represent the number [tex]3.939 \times 10^{6}[/tex] in standard decimal notation.
In this case we need to move the decimal point based on the power of 10.
In our case power of 10 = 6.
Let’s first take a number without [tex]10^6[/tex] and add six zeros on right.
So we get 3.939000000
Now multiplying above number by [tex]10^6[/tex] means moving the decimal after 6 numbers from the current position, that means
[tex]3.939 \times 10^{6}=3939000.00[/tex]
That is 3939000 is required standard decimal notation of scientific notation number [tex]3.939 \times 10^{6}[/tex]
