(10^8)– (10^2)/(10^-7) – (10^-3)
What is the approximate value of the equation
A. 1
B. 10
C. 10^2
D. 10^3
E. 10^4
The answer was B. I am wondering if any one can help me follow the logic because when I work through I do not get 10. I get something closer to 1

Vishu,
If the denominator is
10 ^ 7 - 10^3 the what u did is right
but may be there is a typo in the problem since the problem reads
10 ^ -7 - 10 ^ -3 like Raun pointed out.
Let me know your thoughts

Vishu,
Thank you fo rthe reponse, but I do not see how 10^8 - 10^3 become 10^2(10^6-1). 10^6-1 is same as 10^6/10^1. Could you please explain the logic behind you factorization . I know that you substract exponents when you divide, but not when you add or substract. Could any one else provide another explanation . Thank you
