Hey guys, it's Kim here. Just in our recent class, we worked on doing word problems with exponents, following the steps of BEDMAS. Here is an example of a problem from our booklet:

Jessica was given the problem below to evaluate. She made an error and got the wrong answer. Find the step where Jessica made her error and then find the correct answer.

48/(2)^3+5(-3)^2

Jessica's work:

= 48/6+5(9)

=8+5*9

=8+45

=53

First, you have to find the value of the numbers with the exponents in the parenthesis.

=48/8+5(9)

And then you follow the steps in BEDMAS. If you don't recall what BEDMAS stands for, it means Brackets, Exponents, Division, Multiplication, Addition, Subtraction. So then that means, we do division now.

=6+5(9)

Then we do multiplication.

=6+45

And then we just add them.

=51

The error that Jessica made in her equation was that instead of (2)^3 = 8, she put that (2)^3 was equal to 6. I hope this post helped even just a tiny bit. If you're still confused, here are some links to useful information about:
