Evaluate 6k - j to the second power + 2k divided by l when j = 5,k= 12, and l = 3.

To evaluate the given expression, we substitute the values of j, k, and l into the expression:

6k - j^2 + 2k/l

When j = 5, k = 12, and l = 3, we have:
6(12) - 5^2 + 2(12)/3

Simplifying each term:
72 - 25 + 24/3

Performing the division:
72 - 25 + 8

Simplifying further:
47 + 8

Finally, adding:
55

Therefore, the value of 6k - j^2 + 2k/l when j = 5, k = 12, and l = 3 is 55.
