\sqrt{n}>25 --> n>25^2.
Divide both parts by 25: \frac{n}{25}>\frac{25^2}{25} --> \frac{n}{25}>25. The only answer choice that is greater than 25 is 26.
Answer: E.
Hello,
I am confused on how to comprehend this question. I understand we are not looking for the value of n and that we are looking for the value of n/25, however, how are you dividing both sides of the inequality: n>25^2 by 25?
What do you mean by "how"? Just divide both sides of n>25^2 by 25.
