The value of ⁻¹( 3 ) + ⁻¹(-2) - ⁻¹ (- 1 2 ) is

Options

  1. A5 6
  2. B2 3
  3. C7 6
  4. D4 3

Correct answer

C. 7 6

Step-by-step solution

The principal value of ⁻¹( 3 ) is 3 . The principal value of ⁻¹(-2) is - ⁻¹(2) = - 3 = 2 3 . The principal value of ⁻¹ (- 1 2 ) is - 6 . Substituting these values into the given expression: 3 + 2 3 - (- 6 ) = + 6 = 7 6 Answer: 7 6
