Question

Simplify 3j - {2k - [5h - (3j k)]}.

Answer 1

Start with the ()
5h-3j-k since you cant add any further u just multiple the second neg in the []

-5h+3j+k+2k you can add ONLY the K

-5h+3j+3k now multiply the neg again this time tih the {}

3j+5h-3j-3k The 3J is canceled out b/c 3j-3j=0
Giving you a total of 5h+3k
