Which of these countries has the greatest population density? Which has the least? Provide an explanation and proof for your answer to receive full credit.

9514 1404 393

Step-by-step explanation:

It is convenient to let a spreadsheet do the repetitive operation of dividing the population by the area. The attached shows ...

  Romania has the greatest population density (95/km²).

  U.S. has the least population density (29/km²).

__

Ghana's population density (77/km²) is neither least nor greatest.

none of the option is correct.

step-by-step explanation:

it says to find which expression equals 9^3 sqrt 10 = ?

9^3 sqrt 10 = 729 sqrt 10.

checking option a. 5 sqrt 10 + 4 sqrt 10

5 sqrt 10 + 4 sqrt 10

= 9 sqrt 10.

checking option b. 5^3 sqrt 10 + 4^3 sqrt 10

5^3 sqrt 10 + 4^3 sqrt 10

= 125 sqrt 10 + 64 sqrt 10

= 189 sqrt 10.

checking option c. 5 sqrt 10 + 4^3 sqrt 10

5 sqrt 10 + 4^3 sqrt 10

= 5 sqrt 10 + 64 sqrt 10

= 69 sqrt 10.

checking option d. 5^3 sqrt 10 + 4 sqrt 10

5^3 sqrt 10 + 4 sqrt 10

= 125 sqrt 10 + 4 sqrt 10

= 129 sqrt 10.

hence, none of the option is correct.

i am thinking c. sorry if im wrong .
