Respuesta :
1) Difference of the populations of Germany and Brazil = 1.16 X 10^8
2) Difference of the populations of Brazil and the United States = 1.2 X 10^8
3) Sum of the populations of Brazil and Germany = 2.76 X 10^8
4) Sum of the populations of the United States and Brazil = 5.12 X 10^8
According to the statement
we have given that the populations of three countries which are
United States is 3.16 × 10^8 and Brazil is 1.96 × 10^8 and Germany is 8.0 × 10^7
And we have to arrange the sums and differences in increasing order of their values.
so, we have to find the
a) the difference of the populations of Germany and Brazil
So,
Difference of the populations of Germany and Brazil = 1.96 X 10^8 - 8 X 10^7 = 116000000 = 1.16 X 10^8
And then we have to find the
b) the sum of the populations of the United States and Brazil
So,
Sum of the populations of the United States and Brazil = 3.16 X 10^8 + 1.96 X 10^8 = 512000000 = 5.12 X 10^8
And then we have to find the
c) the difference of the populations of Brazil and the United States
So,
Difference of the populations of Brazil and the United States = 3.16 X 10^8 - 1.96 X 10^8 = 120000000 = 1.2 X 10^8
And then we have to find the
d) the sum of the populations of Brazil and Germany
So,
Sum of the populations of Brazil and Germany: 1.96 X 10^8 + 8 X 10^7 = 276000000 = 2.76 X 10^8
NOW, we arrange the sum and difference in increasing order of their values.
So,
1) Difference of the populations of Germany and Brazil = 1.16 X 10^8
2) Difference of the populations of Brazil and the United States = 1.2 X 10^8
3) Sum of the populations of Brazil and Germany = 2.76 X 10^8
4) Sum of the populations of the United States and Brazil = 5.12 X 10^8
