Hello My Dear RU-vid Family 😍😍😍 Hope you all are doing well 🥰🥰🥰 If you are enjoying my video about how to solve this math olympiad algebra problem then please Like and Subscribe my channel as it helps me a lot 🙂🙂🙂
Managed to find x = 4 by doing: sqrt(x)^sqrt(x) = x (x^(1/2))^(sqrt x) = x x^(1/2 * sqrt x) = x x^(1/2 * sqrt x) = x^1 1/2 * sqrtx = 1 sqrt x = 2 x = 4 Seems like there's some error in that work that eliminates 1 though
I feel like this is the intended way and 1 is just supposed to be common sense so the answer is 1,4 I used the same method for 4 but 1 just made sense so I put that in as well
