Surface (area) of a star = 10^15 sq miles. Surface (area) of our planet = 10^11 sq miles. [I Like Mathematics]

@ozgirl512 Yup
Could you please explain

@Riemann You subtract one power from the other to get the difference, 10^4... Which is 10,000

@ozgirl512 So,
10^15 = 1000000000000000
-
10^11 = 100000000000

= 99900000000000

Then?

@Riemann Don't bother to convert them from powers, there's no need..10^15 minus 10^11 equals 10^4 which equals 10,000

@ozgirl512 An exercise of a standard form, so I am doing that for practice. Pls help.

@Riemann a difference of 10^4 technically is not wrong but you cannot simply subtract the multiples because they are multiplied by the power of, not by the number of...
Your example was correct, thats a difference of 999 trillion. Not 10000.

@krf336 I think we may be taking at crossed proposes... Maybe I think lol... I thought he was after the difference in area between the two, not the area itself...a size difference of 999 trillion times seems a tad excessive

@krf336@ozgirl512 I was trying to find a way to use 9.999*10^14. You people got it right tho.

@ozgirl512 It does seem huge, but the numbers don't lie. Unless math is wrong, which i sometimes wonder... lol

@krf336 I think one approach is working out the area, whilst the other is working out the difference between the two areas ...

@ozgirl512 yup
