\( \Large \sqrt{289} - \sqrt{625} \div \sqrt{25} \) is equal to

A) 17
B) 15
C) 12
D) \( \Large - \frac{8}{5} \)

Correct Answer:



C) 12

Description for Correct answer:
\( \Large \sqrt{289} - \sqrt{625} \div \sqrt{25} \)

= \( \Large \sqrt{17 \times 17} - \sqrt{25 \times 25} \div \sqrt{5 \times 5} \)

= \( \Large 17 - 25 \div 5 = 17 - 5 = 12 \)
