10^196 - 10^9 = Which of the following best approximates the value of the expression above?  Choose the correct choice from the following answers:	A) 10^186	B) 10^196	C) 10^100	D) 10^150	E) 10^170
10^196 - 10^9 =   Which of the following best approximates the value of the expression above?   Yes, answer 10^196 is correct. Note that we need approximate value of the given expression and as 10^(196) is much larger number than 10^(9) then 10^(9) is pretty much negligible in this case: 10^(196)-10^(9)=~10^(196).   Answer : 10^196
