The value of [ ⁻¹ ( 4 5 )+ ⁻¹ ( 2 3 ) ] is

Options

  1. A17 6
  2. B16 7
  3. C6 17
  4. D7 16

Correct answer

A. 17 6

Step-by-step solution

The value of [ ⁻¹ ( 4 5 )+ ⁻¹ ( 2 3 ) ] is to be found out. Let ⁻¹ ( 4 5 )= = 4 5 = 3 5 = 3 4 = ⁻¹ ( 3 4 ) Hence given expression. array l = [ ⁻¹ ( 3 4 )+ ⁻¹ ( 2 3 ) ]= [ ⁻¹ ( 3 4 + 2 3 1- ( 3 4 ) ( 2 3 ) ) ] = [ ⁻¹ ( 17 6 ) ]= 17 6 array
