Given that a * b = \(\frac{a + b}{\text{ab}}\) + (a - b). Find the value of 3 * 2
-6
\(\frac{11}{6}\)
\(\frac{6}{11}\)
-1 \(\frac{5}{6}\)
Explanation
Given that a * b = \(\frac{a + b}{\text{ab}}\) + (a - b)
3 * 2 = Given that a * b = \(\frac{3 + 2}{3.2}\) + (3 - 1)
= \(\frac{5}{6}\) + 1 = \(\frac{5}{6}\) + \(\frac{6}{6}\) = \(\frac{11}{6}\)
