-270
on expanding
= -36+9{6-32}
= -36+9{-26}
= -36-234
= -270

Solve according to order of operations ... PEMDAS >>>
( ), exponents, multiplication, division, addition and subtraction
- 4(9) + 9[6 - 8(2)(2)]
- 36 + 9[6 - 8(4)]
- 36 + 9[6 - 32]
- 36 + 9[- 26]
- 36 - 234
- 270

You want to use PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction) in this problem:
You have have to work out the problem starting in the parentheses or brackets:
[6-8(2)^2]
[6-8(4)]
[6-32]
[-26]
-4(9)+9[-26]
Now, you do the multiplication:
-36+-234
The final step is to add:
-36+-234=-270

this cannot be solve except if [ and } are the same. assuming they are the same then
= -4(9)+9[ 6-8(2)2 }
first remove the inner bracket
= -4(9)+9[6-16*2 }
then multiply 16*2=32
= -4(9)+9 [ 6-32 }
opening all the brackets
= -36+54-288=-270
= -270

-4(9)+9[6-8(2)2]
the order of operation requires you to solve the inner most set of brackets 1st operating from left to right.
step1.
-4(9)+9 [ 6 -(16)2 ]
step2.
-4(9)+9[6-32]
step 3.
-4(9)+54-288
step 4.
-36 + ( -234)
-270

-4(9)+9[6-8(2)2]
-36 + 9[6-32]
-36 + 9[-26]
-36 - 234 = -270
Merci~
