Step-by-Step Solution

Step 1: Understand the expression

The given expression is:

[ 6^2 / 3(2) / 6 ]

Here, we need to carefully consider the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (left to right), Addition and Subtraction (left to right)).

Step 2: Evaluate the exponent

First, calculate the exponent (6^2):

[ 6^2 = 36 ]

So, the expression now looks like:

[ 36 / 3(2) / 6 ]

Step 3: Handle multiplication and division from left to right

Next, we move on to the division and multiplication operations. According to PEMDAS, we handle multiplication and division from left to right.

First, divide 36 by 3:

[ 36 / 3 = 12]

The expression now is:

[ 12*2 / 6 ]

Then, multiply 12 by 2:

[12*2 = 24]

Now, we have:

[24 / 6]

Finally, divide 24 by 6:

[ 24 / 6 = 4 ]

Final answer

The value of the expression ( 6^2 / 3(2) / 6 \) is 4.

This brain teaser is a great example of why it’s essential to follow the order of operations carefully. Missing a step or misinterpreting the sequence can lead to incorrect results. By breaking down the problem systematically, we can confidently solve it and reinforce our understanding of fundamental principles in Mathematics.
