Simplify the expression 4^2 + 8 ÷2
To simplify the expression `4^2 + 8 ÷ 2`, we start by performing the division operation of 8 by 2, which gives us 4.
Now, we need to calculate 4^2, which is 4 multiplied by itself: 4^2 = 4 * 4 = 16.
Finally, we can substitute these values back into the original expression:
4^2 + 8 ÷ 2 = 16 + 4 = 20.
Therefore, the simplified expression is 20.
To simplify the expression 4^2 + 8 ÷ 2, follow these steps:
Step 1: Evaluate the exponent
4^2 = 4 × 4 = 16
After evaluating the exponent, the expression becomes:
16 + 8 ÷ 2
Step 2: Evaluate the division
8 ÷ 2 = 4
After evaluating the division, the expression becomes:
16 + 4
Step 3: Add the two numbers together
16 + 4 = 20
Therefore, the simplified expression is 20.
