Question

How to work it and the answer

Answer 1

Firstly the lines around -14 mean the "absolute value" which means, ignore the sign , it will be always positive. So, 3 (14) is 42.

Now let's go for the 8-11 = -3
now when you cube this number, the result will be negative. 
-3 x -3 x -3 = -27.

however, there is a negative sign outisde the brackets, so - (-27) = + 27..
  
 so the result so far is +27 +42 = 69

Now below the line, we have 2^4 = 2 x 2 x 2 x 2  or 4 x 4 = 16 , and then -7 which is 9. 

So, what we end up with is 69/9
