Thank you for using the timer!

There are many benefits to timing your practice, including:
Fozzzy, which example method you are referring to. If \(n^4<25\), you can consider 1 & 2 as only positive numbers which satisfy the condition.
The earlier explanation said 3^4 was satisfying the condition so that got me confused, Only 1 and 2 satisfy the equation. when we combine 1=1^2 so this case is ruled out leaving us with the only possible value as 2.
The fastest way to approach these questions is using examples, I was wondering if there is a graphic approach or any alternative solution in case the question is complex. _________________
