Mark the correct alternative in each of the following: If the binary operation * on Z is defined by a * b = a 2 – b 2 + ab + 4, then value of (2 * 3) * 4 is

Question

Philoid · Accepted Answer

Given that a * b = a² – b² + ab + 4

To calculate (2 * 3) * 4

⇒ 2 * 3 = 2² – 3² + 2.3 + 4 = 5

⇒ (2 * 3) * 4 = 5 * 4

⇒ 5 * 4 = 5² – 4² + 5.4 + 4

= 33
