Final answer:
To evaluate the expression 42 + 5 × 32 - 42 ÷ 23, we need to follow the order of operations (PEMDAS). The value of the expression is approximately 200.17391304.
Step-by-step explanation:
To evaluate the expression 42 + 5 × 32 - 42 ÷ 23, 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).
First, we perform the multiplication: 5 × 32 = 160.
Then, we perform the division: 42 ÷ 23 ≈ 1.82608696 (rounded to 8 decimal places).
Finally, we perform the addition and subtraction: 42 + 160 - 1.82608696 = 200.17391304 (rounded to 8 decimal places).
Therefore, the value of the expression is approximately 200.17391304.
