London has a population of 2x10^4 and new york has a population of 6x10^5. find which population is bigger and by how much.

 New York population is bigger by 580,000 ,which can be written in standard form as 5.8 x

Step-by-step explanation:

2 x can be written in ordinary number as 20,000

6 x can be written in ordinary number as 600,000

With this , it is clear that New York has a larger population.

The difference in their population will be

600,000 - 20,000 = 580,000

not sure about this one man

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
