Options

  1. A2
  2. B- 2
  3. C1 2
  4. D- 1 2

Correct answer

C. 1 2

Step-by-step solution

The given expression is 15^ - 15^ . Multiplying and dividing by 2 , we get: 2 ( 1 2 15^ - 1 2 15^ ) Substituting 1 2 = 45^ = 45^ : 2 ( 45^ 15^ - 45^ 15^ ) Using the identity A B - A B = (A + B) : 2 (45^ + 15^ ) 2 60^ 2 1 2 = 1 2 Answer: 1 2
