The integer x is how much greater than 3?
(1) \(10^x = 100,000\)
(2) \(\frac{1}{10^x} = 0.00001\)
(1) \(10^x = 100,000\)
(2) \(\frac{1}{10^x} = 0.00001\)
Every tricky question should trigger a follow up quiz.

1. \(10^x = 100,000\) ==> \(10^x = 10^5\) ==> x=5..... sufficient
2. \(\frac{1}{10^x} = 0.00001\) ==> \(\frac{1}{10^x} = \frac{1}{10^5}\) ==> x=5..... sufficient..... Thus Ans D

Asked: \(x-3 =?\)
1) \(10^x = 10^5\)
\(x = 5\)
2) \(10^{-x} = \frac{1}{10^5}\) (As \(x^{-1} = \frac{1}{x }\))
\(10^{-x} = 10^{-5}\)
\(x = 5\)
