To simplify the expression 4^2 + 8 ÷ 2, we first need to perform the calculations within the parentheses.
4^2 means 4 raised to the power of 2, which is equal to 4 multiplied by itself: 4^2 = 4 * 4 = 16.
Then, we divide 8 by 2: 8 ÷ 2 = 4.
Finally, we add our results together: 16 + 4 = 20.
Therefore, the correct answer is 20.
To simplify the expression 4^2 + 8 ÷ 2, we follow the order of operations.
First, we calculate the exponent, which is 4^2.
4^2 = 4 * 4 = 16.
Next, we divide 8 by 2.
8 ÷ 2 = 4.
Finally, we add the results of the exponent and the division.
16 + 4 = 20.
Therefore, the simplified expression is 20.
The correct option is: 20.
To simplify the expression 4^2 + 8 ÷ 2, we need to follow the order of operations, which states that we should solve any calculations within parentheses first, then any exponents, followed by any multiplication or division from left to right, and finally any addition or subtraction from left to right.
Let's break down the expression step by step:
1. Calculate the square of 4: 4^2 = 4 * 4 = 16.
2. Divide 8 by 2: 8 ÷ 2 = 4.
3. Add the results together: 16 + 4 = 20.
Therefore, the simplified expression is equal to 20.
