insert grouping symbols into 2*3^3+4 to get it to equal 4374
is that even possible!? did you write the question correctly?
thats what it says in my alg.1 book?
2*3^3+4 grouped as
2*(33+4) =
2*(37) =
2*2187 = 4374.
Ta-dah!!
THANK YOU!

To insert grouping symbols into the expression 2*3^3+4 to make it equal 4374, you need to modify the order of operations in the expression. The order of operations states that you should first perform any calculations inside parentheses, then exponentiation, multiplication and division (from left to right), and finally addition and subtraction (from left to right).
Let's break down the original expression step by step:
2*3^3+4
First, perform the exponentiation:
3^3 = 27
So, the expression becomes: 2*27+4
Next, perform the multiplication:
2*27 = 54
So, the expression becomes: 54+4
Finally, perform the addition:
54+4 = 58
As you can see, the original expression evaluates to 58, not 4374. Therefore, we need to add grouping symbols to change the order of operations.
To make the expression equal 4374, we can add grouping symbols to ensure that the exponentiation is performed first. We can accomplish this by grouping (2*3^3) using parentheses like this:
(2*3^3) + 4
Now, let's evaluate the expression with the updated grouping symbols:
First, perform the exponentiation inside the parentheses:
3^3 = 27
So, the expression becomes: 2*27 + 4
Next, perform the multiplication:
2*27 = 54
So, the expression becomes: 54 + 4
Finally, perform the addition:
54 + 4 = 58
As you can see, even with the updated grouping symbols, the expression evaluates to 58, not 4374. It appears there may be a mistake in the given task, as there is no way to insert grouping symbols to make the expression equal 4374.
