Question

Simplify 8 + (3^2 - 4)

Answer 1

Answer:

=13

*The answer must have a positive sign.*

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!

Answer 2

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!
