Final answer:
After carefully evaluating each provided expression, none of them is equal to 10. If there are no typos in the question, it appears to be incorrect as provided. An example of an expression that would equal 10 is the square root of 100.
Step-by-step explanation:
The question asks us to find which of the provided expressions is equal to 10. Let's evaluate each option step-by-step:
- A. 27 + 149 - This sum is obviously more than 10 since both addends are greater than 10.
- B. 964 + 18 - Similar to option A, this sum is far greater than 10.
- C. 181 - √9 - The square root of 9 is 3, so 181 - 3 = 178, which is not equal to 10.
- D. √121 - 7 - The square root of 121 is 11, and 11 - 7 = 4, which is also not equal to 10.
It seems none of the provided options mathematically evaluate to 10. Based on the information provided and potential options, there might be a mistake in the question as none of the expressions are equal to 10. However, if we were tasked with finding an expression that equals 10, an example could be √100, since the square root of 100 is indeed 1
