(2^3) - [2^2(2(3 - 2^2))] + [2^2(2*3 - 2^2)]
First: solve the expression according to order of operations >>>
>>PEMDAS > ( ), exponents, multiplication, division, addition & subtraction.
(2^3) - [2^2(2(3 - 4))] + [2^2(6 - 4)]
(2^3) - [2^2(2(-1))] + [2^2(2)]
(2^3) - [2^2(-2)] + [2^2(2)]
(2^3) - [4(-2)] + [4(2)]
(2^3) - [-8] + [8]
(2)(2)(2) - [-8] + [8]
8 - [-8] + [8]
8 + 8 + 8
16 + 8
= 24

2³ - 2²[2(3 -2²) + 2²(2 x 3 - 2²)]
2³ - 2²[ 2(3 - 4) + 2²(6 - 4)]
2³ - 2²[ 2(-1) + 4(2)]
2³ - 2²[ - 2 + 8]
2³ - 2²[ 6]
8 - 4[ 6 ]
8 - 24
- 16
The answer is - 16

I agree with Eva , the answer is -16
Step1: Let's get rid of the expodentials since they are small
8-4(2(-1)+4(6-4))
Step2: Let's follow order of operation and get rid of the parantheses
8-4(-2+8)
Step3: -4 X 6 = -24
Step4: 8-24= -16

remember BEDMAS (Brackets, exponents, division, multiplication, addition, and subtraction)
first look at the brackets and simplify what you can
2^3 - 2^2 [2*(3-4) + 4(6-4)]
2^3 - 2^2[2*-1 + 4*2]
2^3 - 2^2[-2+8]
2^3 - 2^2[6]
exponents
8 -4[6]
multiplication
8-24
subtraction

you do the perenthases first 2^3-2^2(2(3-2^2)+2^2(2*3-2^2)) is the same as 2^3-2^2(2(-1)+2^2(2)) . then u do perenthases again so... 8-2^2((-2)+4(2))...8-2^2(-2+8)..so it is..8-2^2(6).....8-4(6).....
8-24... so it is -16

2^3-2^2(2(3-2^2)+2^2(2*3-2^2))
8-4(2(3-4)+4(6-4))
8-4(2(-1)+4(2))
8-4(-2+8)
8-4(6)
8-24
-16
I don't know how the second person got 4 but the third person didn't get the parentheses right

=8-4(2(3-4)+4(8-4)= 8-4(-2+4x4) =8 - 4(-2 +16)=8-4(14)=
=8-56=-48
