If \(\frac{a}{b}\) + \(\frac{b}{a}\) = 2
Find \(\frac{a\;+\;b}{ab}\).
Answer & explanation
Correct answer: option 2
Formula → x + \(\frac{1}{x}\) = 2, then x = 1 always
Put \(\frac{a}{b}\) = 1
\(\frac{b}{a}\) = 1
\(\frac{a\;+\;b}{ab}\) = 2
If \(\frac{a}{b}\) + \(\frac{b}{a}\) = 2
Find \(\frac{a\;+\;b}{ab}\).
Correct answer: option 2
