Question

Simplify -3[4-2(3^2)] show work

Answer 1

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.`

Answer 2

42

Explanation:

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

-3[4 - 2(9)]

-3[4 - 18]

-3[-14]

= 42
