Some of the equations are provided below with symbols and mathematical relations you have to check which of the following combination is correct If A • B = (A - B)2 + B, then 5 • 2 is?
11
The operation is defined as A • B = (A − B)2 + B.
For 5 • 2: A − B = 5 − 2 = 3.
(3)2 = 9.
9 + B = 9 + 2 = 11.
Hence, 5 • 2 = 11.
