Final answer:
To find the value of 4 & 6, substitute a = 4 and b = 6 into the expression a & b = 2a + b^2. The value of 4 & 6 is 44.
Step-by-step explanation:
To find the value of 4 & 6, we substitute a = 4 and b = 6 into the expression a & b = 2a + b^2.
So, 4 & 6 = 2(4) + 6^2 = 8 + 36 = 44.
Therefore, the value of 4 & 6 is 44.
