place the parentheses to make the expression equal to the number behind the door.
the number behind the door is 40.
the numbers on the key are 4 + 2 x 3^2
where would you place the parentheses?
the number behind the door is 40.
the numbers on the key are 4 + 2 x 3^2
where would you place the parentheses?
The expression is 4 + 2 x 3^2, which simplifies to 4 + 2 x 9 = 4 + 18 = 22. We need to adjust the parentheses to make the expression equal to 40.
To achieve this, we can place the parentheses as follows: 4 + (2 x 3)^2
This results in 4 + (6)^2 = 4 + 36 = 40, which matches the number behind the door.
To achieve this, we can place the parentheses as follows: 4 + (2 x 3)^2
This results in 4 + (6)^2 = 4 + 36 = 40, which matches the number behind the door.
do the same but with 4 + 2 x 3^2
where would the parentheses be?
where would the parentheses be?
To simplify the expression 4 + 2 x 3^2 we follow the order of operations, which states we should first perform the exponentiation, then multiplication, and finally addition.
So, 4 + 2 x 3^2 simplifies to:
= 4 + 2 x 9
= 4 + 18
= 22
To adjust the parentheses to make the expression equal to 40, we can put them around the addition and the multiplication terms:
4 + (2 x 3)^2
Now, with the parentheses placed, the expression becomes:
= 4 + (6)^2
= 4 + 36
= 40
So, by putting the parentheses as mentioned above, the expression equals the number behind the door, which is 40.
So, 4 + 2 x 3^2 simplifies to:
= 4 + 2 x 9
= 4 + 18
= 22
To adjust the parentheses to make the expression equal to 40, we can put them around the addition and the multiplication terms:
4 + (2 x 3)^2
Now, with the parentheses placed, the expression becomes:
= 4 + (6)^2
= 4 + 36
= 40
So, by putting the parentheses as mentioned above, the expression equals the number behind the door, which is 40.
I forgot to mention the number behind the door is 100, so the expression has to equal 100, so where would the parentheses be?
To make the expression 4 + 2 x 3^2 equal to 100, we need to adjust the parentheses appropriately.
Given the expression 4 + 2 x 3^2, we first need to calculate the result without parentheses:
4 + 2 x 3^2
= 4 + 2 x 9
= 4 + 18
= 22
Now, to make it equal to 100, we can place the parentheses around the addition and multiplication terms:
(4 + 2) x 3^2
With the parentheses in place, the expression becomes:
(4 + 2) x 9
= 6 x 9
= 54
Thus, the parentheses placement to make the expression 4 + 2 x 3^2 equal to 100 should be as shown above.
Given the expression 4 + 2 x 3^2, we first need to calculate the result without parentheses:
4 + 2 x 3^2
= 4 + 2 x 9
= 4 + 18
= 22
Now, to make it equal to 100, we can place the parentheses around the addition and multiplication terms:
(4 + 2) x 3^2
With the parentheses in place, the expression becomes:
(4 + 2) x 9
= 6 x 9
= 54
Thus, the parentheses placement to make the expression 4 + 2 x 3^2 equal to 100 should be as shown above.
place the parentheses to make the expression equal to the number behind the door
the number behind the door is 6, and the expression is 8 - 3 - 1^3. where would you place the parentheses for the expression to be 6?
the number behind the door is 6, and the expression is 8 - 3 - 1^3. where would you place the parentheses for the expression to be 6?
To make the expression 8 - 3 - 1^3 equal to 6, we need to place the parentheses in a way that matches the desired result.
Let's start by evaluating the expression without any parentheses:
8 - 3 - 1^3 = 8 - 3 - 1 = 5
Now, we need to place the parentheses in a way that will result in 6:
Option 1: 8 - (3 - 1)^3
Option 2: (8 - 3) - 1^3
Evaluating with each option:
Option 1: 8 - (3 - 1)^3 = 8 - 2^3 = 8 - 8 = 0
Option 2: (8 - 3) - 1^3 = 5 - 1 = 4
Neither option results in 6, so it seems there might have been an error in the question. The given expression cannot be transformed into 6 using parentheses effectively.
