If P#Q means P+Q/2, then 6#8 means 6+8/2 which is equal to 6+4 which is equal to 10. Therefore, 6#8 = 10.
Now, we can say that 3#(6#8) is also equal to 3#10 since 6#8=10. Then according to the general rule, 3#10 is equal to 3+10/2 which is equal to 3+5 which is equal to 8.

Therefore, 3#(6#8) is 8.
