Assertion (A): 8^x + 2 + 8^x + 1/8^x + 2 - 8^x + 1 = x + 2 + x + 1/x + 2 - x - 1 = 2x + 3. Reason (R): 8^x + 2 + 8^(x + 1)/8^x + 2 - 8^x + 1 = 8(x + 2 + x + 1)/8(x + 2 - x - 1) = x + 2 + x + 1/x + 2 - x - 1 = 2x + 3 1. A is true, R is false. 2. A is false, R is true. 3. Both A and R are true. 4. Both A and R are false.
