Simplify the expression 4^2 + 8 ÷ 2

To simplify the expression 4^2 + 8 ÷ 2, follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction):

First, simplify the exponent: 4^2 = 16.

Now, the expression becomes 16 + 8 ÷ 2.

Next, perform the division: 8 ÷ 2 = 4.

The expression is simplified to 16 + 4.

Finally, perform the addition: 16 + 4 = 20.

Therefore, the simplified expression is 20.

sqrt of 25

The square root of 25 is 5.

sqrt of 0.81

The square root of 0.81 is 0.9.

To simplify the expression 4^2 + 8 ÷ 2, we follow the order of operations (also known as PEMDAS).

Step 1: Calculate the exponent 4^2. 4^2 means 4 raised to the power of 2, which is 4 * 4 = 16.

Step 2: Divide 8 by 2. 8 ÷ 2 = 4.

Step 3: Add the results from step 1 and step 2. 16 + 4 = 20.

Therefore, the simplified expression is 20.

To simplify the expression 4^2 + 8 ÷ 2, we follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).

First, we solve any exponents. In this case, 4^2 means 4 raised to the power of 2, which is 4 x 4 = 16.

Now, we have the simplified expression 16 + 8 ÷ 2.

Next, we perform the division operation, starting from the left: 8 ÷ 2 = 4.

The expression now becomes 16 + 4.

Finally, we perform the addition operation: 16 + 4 = 20.

Therefore, the simplified expression is 20.
