Evaluate the following expression.
7^0
To evaluate an expression, you need to follow the correct order of operations, which is commonly known as PEMDAS. Let's break down each expression:
1. 4 * 4 - 14 / 2 + 6
- First, we perform the division: 14 / 2 = 7.
- Then, we perform the multiplication: 4 * 4 = 16.
- Now we have: 16 - 7 + 6.
- Finally, we perform the addition and subtraction from left to right: 16 - 7 = 9, then 9 + 6 = 15.
Therefore, the answer is 15.
2. 2 * [1 + (19 + 13) / 4]
- Inside the parentheses, we perform the addition: 19 + 13 = 32.
- Then, we divide 32 by 4: 32 / 4 = 8.
- Now we have: 2 * [1 + 8].
- Continuing inside the brackets, we perform the addition: 1 + 8 = 9.
- Now we have: 2 * 9.
- Finally, we perform the multiplication: 2 * 9 = 18.
Therefore, the answer is 18.
3. 50 + 25 / 5^2
- First, we calculate the exponentiation: 5^2 = 25.
- Then, we perform the division: 25 / 25 = 1.
- Now we have: 50 + 1.
- Finally, we perform the addition: 50 + 1 = 51.
Therefore, the answer is 51.
By following the order of operations, you can evaluate expressions correctly.
