What is the value of 7² - 10?

• A. 49
• B. 39
• C. 45
• D. 40

Answer: (B)

To find the value of \( 7^2 - 10 \), start by calculating \( 7^2 \). This is the square of 7, which equals \( 49 \) because \( 7 \times 7 = 49 \). Next, subtract 10 from 49. Performing the subtraction: \[ 49 - 10 = 39 \] Thus, the final result of \( 7^2 - 10 \) is \( 39 \). This shows that option B is indeed the correct answer. When dealing with similar problems, remember to first compute any exponentiation before performing subtraction or other operations, as the order of operations influences the outcome.

To find the value of ( 7^2 - 10 ), start by calculating ( 7^2 ). This is the square of 7, which equals ( 49 ) because ( 7 \times 7 = 49 ).

Next, subtract 10 from 49. Performing the subtraction:
