Given in the question:
a.) Houston area = 2.69 x 10^5 square miles
b.) Greensboro area = 1.21 x 10^3 square miles
To be able to subtract the two areas in scientific notation, we must first make them similar in terms of the exponent.
We get,
[tex]\text{ 2.69 x 10}^5=269.00x10^3[/tex][tex]1.21x10^3\text{ ; Adapt the notation.}[/tex]
Let's now proceed with the subtraction,
[tex](269.00x10^3_{})-(1.21x10^3)[/tex][tex]\text{ = (269.00 - 1.21) x 10}^3[/tex][tex]\text{ = 267.79 x 10}^3or2.6779x10^5[/tex]
The difference between the area of Houston and Greensboro is 2.6779 x 10^5.
