(1/2) • 4^2 - (4-6)/2
To solve the expression (1/2) • 4^2 - (4-6)/2, we start by evaluating the exponents:
4^2 = 4 • 4 = 16
Then, we can simplify the expression further:
(1/2) • 16 - (4-6)/2
= 8 - (-2)/2 [Evaluating 16 divided by 2]
= 8 + 2/2 [Changing the subtraction of -2 to addition of 2]
= 8 + 1 [Evaluating 2 divided by 2]
= 9 [Adding 8 and 1]
So, the value of the expression is 9.
To solve the expression (1/2) • 4^2 - (4-6)/2 step-by-step, follow these steps:
1. Start by calculating the value of 4^2, which is 4 multiplied by itself: 4^2 = 4 * 4 = 16.
2. Then, calculate the value inside the parentheses: (4-6) = -2.
3. Calculate (4-6)/2 by dividing -2 by 2: (4-6)/2 = -2/2 = -1.
4. Next, multiply the result of step 1, 16, by 1/2: (1/2) * 16 = 8.
5. Finally, subtract the result obtained in step 3, -1, from the result obtained in step 4, 8: 8 - (-1) = 8 + 1 = 9.
Therefore, the simplified value of the expression (1/2) • 4^2 - (4-6)/2 is 9.
To solve this expression, let's break it down step by step.
First, we need to simplify the exponent. We have 4 raised to the power of 2: 4^2 is equal to 4 multiplied by itself, which is 16.
Next, we have a subtraction inside parentheses.
4 - 6 equals -2.
Now, let's divide -2 by 2. -2 divided by 2 equals -1.
Finally, we have (1/2) multiplied by 16. (1/2) is the same as 0.5, so 0.5 multiplied by 16 is 8.
So, the value of the expression (1/2) • 4^2 - (4-6)/2 is 8.
