Final answer:
The expression can be evaluated by multiplying 24 by 10 and decreasing the exponent of 10 by 7. The result simplifies to 2 times 10^5, which is equal to 200,000.
Step-by-step explanation:
The expression can be evaluated by applying the order of operations, which states that you should perform any operations inside parentheses first, followed by exponents, multiplication and division from left to right, and finally addition and subtraction from left to right. Since there are no parentheses or exponents in the expression, we can simply perform the multiplication and addition.
First, we multiply 24 by 10 to get 240. Then, we subtract 7 from the exponent of 10 to get 5. So, the expression simplifies to 2 × 105, which is equal to 200,000. Therefore, the correct answer is D) 24.
