Let (*) be a binary operation on a natural number defined by a * b = a - b + (ab)2 2 , then find 3 * 5

Let (*) be a binary operation on a natural number defined by a * b = a - b + (ab)2 ${}^2$, then find 3 * 5

Answer Details

3 * 5 = 3 - 5 + (3 x 5)2 ${}^{\mathrm{<br>}}$

-2 + (15)2 ${}^{\mathrm{<br>}}$

-2 + 225
