Question

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

Answer 1

Answer:

42.

Step-by-step 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

Answer:

42

Step-by-step explanation:

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

-3[4 - 2(9)]

-3[4 - 18]

-3[-14]

= 42
