<u><em>Answer:</em></u>

<u><em>=13</em></u>

<u><em>*The answer must have a positive sign.*</em></u>

Step-by-step explanation:

This question's it's about the order of operations. It stands for parenthesis, exponents, multiply, divide, add, and subtract. It can also go left too right. (PEMDAS)

First, do parenthesis.

Then, do exponents first.

(3^2-4)

3^2=3*3=9

8+9-4

Next, add/subtract left too right.

8+9=17

17-4=13

Answer: → =13

Hope this helps!

Thanks!

Hey there!

In order for you to solve this equation you could do PEMDAS, which is ↓

  • Parentheses
  • Exponents
  • Multiplication
  • Division
  • Addition
  • Subtraction

In this particular equation we have ↓

  1. Parentheses
  2. Exponents
  3. Addition
  4. Subtraction

So, the first thing we need to do to solve this equation is solve  what is in the parentheses

(3^2 - 4)

Nextly, we have to do the exponents

3^2

So, let's solve the parentheses & exponents

3^2 =  9

We could now "remove" the parentheses

9 - 4 = 5

Now we could move onto the last step, which is addition

8+5 = 13

\boxed {Answer: 13}

Good luck on your assignment and enjoy your day!
