Evaluate the expression (8/2) + 2^3 - 5
To evaluate the expression, we follow the order of operations: parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).
First, we calculate the exponent: 2^3 = 2 * 2 * 2 = 8.
Now, we substitute the exponent result back into the expression: (8/2) + 8 - 5.
Next, we solve the division: 8/2 = 4.
Our new expression is: 4 + 8 - 5.
Finally, we perform the addition and subtraction from left to right: 4 + 8 = 12, then 12 - 5 = 7.
The final value of the expression is 7.
To evaluate the expression (8/2) + 2^3 - 5, follow these steps:
Step 1: Simplify the division.
8/2 = 4
The expression now becomes 4 + 2^3 - 5.
Step 2: Evaluate the exponentiation.
2^3 = 2 * 2 * 2 = 8
The expression now becomes 4 + 8 - 5.
Step 3: Perform addition and subtraction from left to right.
4 + 8 = 12
12 - 5 = 7
So, (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, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right). Let's break it down step by step:
Step 1: Exponents
In the given expression, there is only one exponent, which is 2^3. To calculate this, we raise the base (2) to the power of the exponent (3), giving us 2^3 = 2 * 2 * 2 = 8.
So far, our expression becomes (8/2) + 8 - 5.
Step 2: Division
Next, we have the division (8/2). To perform this calculation, we divide the numerator (8) by the denominator (2), resulting in 8/2 = 4.
Now, our expression becomes 4 + 8 - 5.
Step 3: Addition and Subtraction
Finally, we have addition and subtraction left in our expression. Starting from left to right, we add 4 + 8, which equals 12. Then, we subtract 5 from 12, giving us 12 - 5 = 7.
Therefore, the value of the expression (8/2) + 2^3 - 5 is 7.
