Evaluate 6k - j2 + 2k \ j, when j = 5,k = 12,and j = 3

To evaluate the given expression when j = 5, k = 12, and j = 3, we substitute the values into the expression:

6k - j2 + 2k \ j = 6(12) - (5)2 + 2(12) \ 5
= 72 - 10 + 24 \ 5
= 62 + 24 \ 5
= 86 \ 5

Therefore, when j = 5, k = 12, and j = 3, the expression 6k - j2 + 2k \ j evaluates to 86 \ 5.
