When multiple operations are involved in an expression, we can utilize the acronym PEMDAS, which is an abbreviation for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. This acronym indicates the order in which these operations should be performed in an expression.
The original problem you listed was E = [(MC)]², where M = 3 and C = 6
In this problem, we have multiple grouping symbols, a set of parenthesis and a set of brackets. First, substitute 3 and 6 for M and C, respectively. Next, work from the inside out with the grouping symbols. In other words, perform the multiplication inside the parenthesis first. Next, raise this product to the second power. That is how we obtain the result 324. Please feel free to reply if you have any further questions.

You're right, Arturo. I looked at it wrong. E = mc² is Einstein's equation. Thanks for explaining this problem to the student.

You are welcome, Michael. Note the student reposted the problem later, but I think she understands your solution now.

Yes, I saw the repost. I guess that my response was not clear enough for her. Thanks again.
