34-(6-7)4 / 23-24

Do the parentheses first. Replace (6-7) by (-1)

34-(6-7)4 / 23-24
becomes
34-(-1)4 / 23-24

Do the exponents next.  Replace 34 by (81)

34-(-1)4 / 23-24
becomes
81-(-1)4 / 23-24

81-(-1)4 / 23-24
becomes
81-(1) / 23-24

81-(1) / 23-24
becomes
81-(1) / (8)-24

81-(1) / (8)-24
becomes
81-(1) / (8)-(16)

Do multiplications and divisions. That is do (1)/(8) and get 1/8, so

81-(1) / (8)-(16)
becomes
81 - 1/8 - 16

Do additions and subtractions:

81 - 1/8 - 16
becomes
648/8 - 1/8 - 16
647/8 - 16
647/8 - 128/8
519/8
