Answer:

42.

Explanation:

Whenever solving problems that include multiple operations, remember this: BPEMDAS:

  • Brackets
  • Parenthesis
  • Exponentiantation (Exponents)
  • Multiplication/Division (Solve whatever comes first)
  • Addition/Subtraction (Solve whatever comes first)


-3[4-2(3^2)]

First, we solve what is in brackets.


[4-2(3^2)]

While solving in brackets, we should still follow the order of operations.

There are no parenthesis, but there are exponents.


3^2=9

Now we are left with:


-3 [4-2*9]

There is multiplication.


2*9=18


-3[4-18]

There is no addition, but there is subtraction.


4 - 18 = -14

Now we are left with:


(-3)*(-14)


(-3)*(-14)=42

Therefore,
-3[4-2(3^2)]= 42.
