Choices:
A) 10^170	B) 10^180	C) 10^(185)	D) 10^160	E) 10^179
10^185 - 10^9 =   Which of the following best approximates the value of the expression above?   Yes, answer 10^185 is correct. Note that we need approximate value of the given expression and as 10^(185) is much larger number than 10^(9) then 10^(9) is pretty much negligible in this case: 10^(185)-10^(9)=~10^(185).   Answer : 10^(185)
