If ⁻¹( )- ⁻¹( )=x , then the value of x is

Options

  1. A^2 2
  2. B2
  3. C2
  4. D^2 2

Correct answer

D. ^2 2

Step-by-step solution

Given the expression x = ⁻¹ ( 1 ( 2 ) ) - ⁻¹ ( ( 2 ) ) . Using the identity ⁻¹(y) + ⁻¹ ( 1 y ) = 2 for y > 0 where y = ( 2 ) , we have: ⁻¹ ( 1 ( 2 ) ) = 2 - ⁻¹ ( ( 2 ) ) Substituting into the expression for x : x = ( 2 - ⁻¹ ( ( 2 ) ) ) - ⁻¹ ( ( 2 ) ) x = 2 - 2 ⁻¹ ( ( 2 ) ) Considering the given alternative form ⁻¹( ) - ⁻¹( ) = x Using ⁻¹ y = 2 - ⁻¹ y : x = ( 2 - ⁻¹( ) ) - ⁻¹( ) x = 2 - 2 ⁻¹( ) To find x : x = ( 2 - 2 ⁻¹( ) ) Using ( 2 - ) = : x = (2 ⁻¹( ) ) Let y = and = ⁻¹(y) , so = y Using the identity (2 ) = 1 -
