Evaluate the expression (8/2)+2^3−5.
To evaluate the expression (8/2)+2^3−5, we follow the order of operations (PEMDAS).
First, we solve the exponent 2^3:
2^3 = 2 × 2 × 2 = 8
Next, we divide 8 by 2:
8/2 = 4
Now, we can substitute these values back into the original expression:
(8/2) + 2^3 − 5 = 4 + 8 − 5
= 12 − 5
= 7
Therefore, the expression (8/2)+2^3−5 evaluates to 7.
To evaluate the expression (8/2) + 2^3 - 5, 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 solve the exponent: 2^3 which is equal to 8.
Next, let's divide 8 by 2: 8/2 = 4.
Now, we have (4) + 8 - 5.
Finally, we can perform the addition and subtraction from left to right: 4 + 8 = 12, then 12 - 5 = 7.
Therefore, the expression (8/2) + 2^3 - 5 evaluates to 7.
To evaluate the expression (8/2) + 2^3 - 5, we follow the order of operations, which is also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).
Step 1: Parentheses
There are no parentheses in this expression, so we can move on to the next step.
Step 2: Exponents
In this expression, we have 2^3. This means we need to raise 2 to the power of 3, which is 2 * 2 * 2 = 8.
Now the expression becomes: (8/2) + 8 - 5.
Step 3: Multiplication and Division
In this expression, we have (8/2). Dividing 8 by 2 equals 4.
Now the expression becomes: 4 + 8 - 5.
Step 4: Addition and Subtraction
Now we add and subtract from left to right.
4 + 8 = 12
12 - 5 = 7
Therefore, the final answer is 7.
