10^190 - 10^9 = Which of the following best approximates the value of the expression above?	Choose the correct choice from the following:  A) 10^170  B) 10^180  C) 10^160  D) 10^181  E) 10^190
10^190 - 10^9 =   Which of the following best approximates the value of the expression above?   Yes, answer 10^190 is correct. Note that we need approximate value of the given expression and as 10^(190) is much larger number than 10^(9) then 10^(9) is pretty much negligible in this case: 10^(190)-10^(9)=~10^(190).   Answer : 10^190
