(3+5)^2 / 2

First we will solve between the brackets.

==> 8^2 /2

Now we will raise to the 2nd power.

==> 64/2 = 32.

==> (3+5)^2 / 2 = 32

( 3 + 5 )2 ÷ 2

To solve this equation remember the order of PEMDAS

Parenthesis

Exponents

Multipication

Division

Addition

Subtraction

Now, to solve this equation you should complete what's inside the parenthesis first with is by adding 3 and 5 together

By adding what's inside the parenthesis your equation should be

8 X 2 ÷ 2 now you have multiply 8 and 2

By multiplying 8 and 2 your equation should look like

16 ÷ 2 now divide 16 by 2

= 8 your answer

( 3 + 5)2/ 2 The first thing to do is follow the PEMDAS rule so add everything up in the parenthesis first.

(8) x 2/ 2 Now multiply the 8 by the 2

16/ 2 = 8 Then divided it by 2 and you have your answer!

or another it can be done and spotted is by...

[ (3 x 2) + (5 x 2) ]/ 2 This is a tad more complicated however it gives the same results! All that was done here was that each number in the parenthesis where multiplied by the two then added up.

[ (6) + (10) ]/ 2

16/ 2 = 8

Use PEMDAS for this

( 3 + 5)2 ÷ 2

(8)2 divided by 2

Now multiply 8 by 2

16 divided by 2

divide by 2 and you have your answer

8

A good way to remember the proper order of operations is BEDMAS.

Brackets, Exponents, Divide, Multiply, Add, Subtract.

In this question the first thing to do is what is in the brackets, (3+5) which is 8.

= (8)2 ÷  2

Then you would do 2÷ 2 which is 1.

=(8)1

You then would multiply the 8 by the 1 which equals 8

=8

It’s important to follow the proper order of operations, or the final answer will be different.

For example (3 + 5)2 ÷ 2,

if someone were to do the middle numbers first,

=3+10÷2, would end up being

=13÷2 which would result in

=6.5

So remember BEDMAS!
