If \(m*n = (\frac{m}{n} – \frac{n}{m}\)) for m, n belong to R, evaluate -3*4
- \(\frac{-25}{12}\)
- \(\frac{-7}{12}\)
-
\(\frac{7}{12}\)
- \(\frac{25}{12}\)
The correct answer is: C
Explanation
\(m*n = \frac{m}{n}-\frac{n}{m}
= \frac{-3}{4} - \frac{4}{-3}
= \frac{-3}{4} + \frac{4}{3}
= \frac{(-9+16)}{12}
= \frac{7}{12}\)
