-(1-2*-2*-2)squared -2*2
To solve this expression, we need to follow the order of operations, which is parentheses, exponents, multiplication/division (from left to right), and addition/subtraction (from left to right).
First, let's simplify the expression inside the parentheses:
-(1 - 2 * -2 * -2)
Inside the parentheses, we multiply -2 by -2. Since two negative numbers multiplied together result in a positive number, -2 * -2 equals 4. Therefore, the expression becomes:
-(1 - 2 * 4)
Next, we simplify the multiplication inside the parentheses:
-(1 - 8)
Multiplying 2 by 4 gives us 8. So, the expression becomes:
-(1 - 8)
Now, let's simplify the subtraction inside the parentheses:
-(1 - 8) equals -(-7) which is the same as 7.
Therefore, the expression becomes:
-7
Finally, let's calculate the final multiplication:
-7 * 2 equals -14.
So, -(1-2*-2*-2)^2 - 2*2 equals -14.
negative (1-2^3)^2-2*2
To solve this expression, let's follow the order of operations:
First, we need to calculate the exponent:
2^3 is equal to 2 * 2 * 2, which equals 8. So the expression becomes:
-(1 - 8)^2 - 2 * 2
Next, we simplify the subtraction inside the parentheses:
(1 - 8) equals -7. Therefore, the expression becomes:
-(-7)^2 - 2 * 2
Now, let's calculate the exponent:
(-7)^2 is equal to (-7) * (-7), which equals 49. So we have:
-49 - 2 * 2
Next, we perform the multiplication:
2 * 2 equals 4. So the expression becomes:
-49 - 4
Finally, we perform the subtraction:
-49 - 4 equals -53.
Therefore, negative (1-2^3)^2 - 2 * 2 equals -53.
To simplify the expression -(1 - 2*-2*-2)^2 - 2*2, follow these steps:
Step 1: Evaluate the expression inside the parentheses, considering the order of operations (parentheses, exponents, multiplication, division, addition, subtraction):
-2*-2*-2 = -8
Step 2: Now substitute the calculated value -8 into the expression:
-(1 - (-8))^2 - 2*2
Step 3: Perform the subtraction inside the parentheses:
-(1 + 8)^2 - 2*2
Step 4: Evaluate the addition inside the parentheses:
-(9)^2 - 2*2
Step 5: Simplify the exponent:
-(81) - 2*2
Step 6: Perform the multiplications and apply the negative sign:
-81 - 4
Step 7: Subtract the two numbers:
-85
Therefore, the simplified value of the expression -(1 - 2*-2*-2)^2 - 2*2 is -85.
