Hello.
Here's our explanation:
This question's it just like order of operations. It stands for p-parenthesis, e-exponents, m-multiply, d-divide, a-add and s-subtract. It can also go left too right.
First, do exponent first.

Then, rewrite the solution to the equation problem down.

Next, you divide by 1 from both sides of an equation.

And finally, simplify.


I hope this helps!
Thank you for posting your question!
Have a great day!
