Question

I really need help with this question! Can somebody solve it and show the steps.....?

Evaluate this expression using the correct order of operations: 2{3 [9 +4 (7 - 5) -4]}

Answer 1

ok so orders of operation.

Explanation:

parenthesis,brachets: 2{3[9+4(2)-4]}

2{3[13×2-4]}

then we take whats inside the brackets and use order of operations there

13×2-4

parenthesis:none

exponents:none

multiplication: 13×2=26

division:none

addition: none

subtraction:26-4=22

then you're left with the equation:

2{3[26]}

clearly we aren't done with the brackets

so we do:

3×26=78

we're left with:

2{78}=156

your answer=156
