5.Find the value of (3+3)^2/6-2x4
I did parenthesis first because of PEMDAS and got 6. The ^2 is outside of the () so do I do 6x6 and get 36 and then continue the rest of the problem?

4. Right

5. Sure, but I'm not sure what you mean by "6-2x4." Online, “*” is used to indicate multiplication to avoid confusion with “x” as an unknown.

To find the day with the biggest difference between high and low temperatures, you need to calculate the difference for each day and compare them. The difference between high and low temperatures can be obtained by subtracting the low temperature from the high temperature.

Let's calculate the differences for each day:

Monday: 106 - 79 = 27
Tuesday: 107 - 79 = 28
Wednesday: 104 - 78 = 26
Sunday: 96 - 74 = 22

As you can see, Tuesday has the biggest difference between high and low temperatures, with a difference of 28 degrees.

Now, let's solve the second question:

The expression is: (3+3)^2/6-2x4

Using the order of operations (PEMDAS/BODMAS), you are correct in starting with parentheses first:

(3+3)^2/6-2x4 becomes (6)^2/6-2x4.

Next, you perform the exponentiation:

(6)^2/6-2x4 becomes 36/6-2x4.

Now, to continue, you need to follow the remaining order of operations:

1. Divide: 36/6 = 6.
2. Multiply: 2x4 = 8.
3. Subtract: 6 - 8 = -2.

Therefore, the value of the expression (3+3)^2/6-2x4 is -2.
