Question

If a * b denotes the larger of 'a' and 'b' and if aob = (a * b) + 3, then write the value of (5) o (10), where * and o are binary operations.

Answer 1

Given: a * b denotes the larger of 'a' and 'b'.
Also, $a\circ b=\left(a*b\right)+3$
For a = 5 and b = 10
a * b = 5 * 10 = 10
$a\circ b=5\circ 10=\left(5*10\right)+3=10+3=13$.
