I don't see it proven that this is the only solution. After all, even with this answer, there's a 3rd and 4th power in the problem. x-y>0 doesn't require both being positive and x>y, it can also be both negative and x<y. That's a path to and set of solutions.

15^30
@mediaguardian 16 วันที่ผ่านมา
The answer is 15^30. You can't cancel exponentiation the same way you cancel divisors.
@nalinivijayan5617 16 วันที่ผ่านมา
My approach is like this 30^60/60^30 , here we can note that power of 30 is n×2 the power of 60 , so on that case 30^2/60^1 = 900/60 = 15 So if it was 30^60 / 60^30 then it will be eqaul to 15^30 as 30^2 / 60^1 = 15 , also 30^4 / 60^2 = 15^2 hence 30^60/60^30 = 15^30
@astrosamurai7135 17 วันที่ผ่านมา
or you could 30th root the whole thing, leaving you with 30^2/60, then simplify 90/60 to 3/2
@astrosamurai7135 17 วันที่ผ่านมา
two steps, much better than the 10 or something shown here.
@Math_with_aram 17 วันที่ผ่านมา
Great solution yes
@letitburn3327 16 วันที่ผ่านมา
You can't do that when it's a simplification problem and not an equation, you could write it as the 30th root of everything to the 30th power so you would get (30^2/60)^30 leaving you with the same solution as the video
@TamirKorem 18 วันที่ผ่านมา
This is inaccurate: There are 4 solutions to this exercise and not only two...: Two of them are real: 1) X+Y = 9 and 2) X+Y=-9 and two of them are complex (imaginary): 3) X+Y = 3i 4) X+Y= - 3i i = is the square root of minus 1
@HUBZONE-19 4 วันที่ผ่านมา

@ksmyth999 18 วันที่ผ่านมา
(x+y)(x-y) = 27. This suggests x+y = 9, x-y =3. So 2x = 12, x = 6, y =3
@TamirKorem 18 วันที่ผ่านมา
You cannot rely on a guess... There are 4 solutions to this exercise and you will miss three of them by using your guess. See my response in the other comments.
@ksmyth999 18 วันที่ผ่านมา
@@TamirKorem Thanks for the comment on my comment. Yes there are four solutions. But my suggestion was not a wild guess, it was a logical conclusion on the assumption one of the solutions would be real integers. That there might be real integer solutions was admittedly a guess, but it was easily testable. The idea of this exercise, in my opinion, was to find one of the roots using the difference of two squares. It was something the presenter had missed. The presenter went on to find the two real solutions. It was good that you pointed out the two complex solutions.

seriously, math olympiad question? first desicion (without math at all) multiplying x*y = -15 it means first (x or y) is with - second (x or y) with + x-y = 8, means x greater than y, so x with + sign y with - sign multiplying gives us nonpair integer and dividing gives us pair integer it means that x is positive nonpair integer y is negative nonpair integer not so hard to solve x = 5 y = -3 5^4 +(-3)^4 = 706 second desicion x - y = 8 => x=8+y y*(8+y) + 15 = 0 y^2 +8*y +15 = 0 y = -3 x=8+y = 5 5^4 +(-3)^4 = 706 why the hell we are playing with formulas when answer is so obvious?

Hi! I don't quite understand... I achieved to isolate the x's with a polynomial which equals to 0 (--> 48x^2-16x+1=0). And i found two roots : 1/4 and 1/12. Of course 1/12 doesn't work, but I don't understand why. Could you explain this to me please ? Thanks
@lightyagami1752 24 วันที่ผ่านมา
Substitute it back into the original equation and you'll find it does not satisfy it. This is a known phenomenon when you take squares or other even higher powers of equations, you may introduce redundant or extraneous roots. This is because by standard convention, sqrt(x) with the usual symbol, only refers to the non-negative square root. But when you square you unwittingly introduce the possibility of including the negative square root. That's why you need to check every single solution by substitution into the original equation.

@tejasvadhyani7860 24 วันที่ผ่านมา
@@lightyagami1752 I think 1/12 is a valid value since sqrt(25) = -5 as well. Since the degree is 2, we would get 2 zeroes(values)

If you cannot notice such elegant polynomial transformations and factorizations. Let f(x) = x⁹+x⁶-36 => f'(x) = x⁵(9x³+6) => f'(x) < 0 <=> x is in interval (-⅔^⅓, 0) => for all x < 0 f(x) <= f(-⅔^⅓) < 0 (since the function is increasing until -⅔^⅓ and then decreasing afterward until 0.) => there are no solutions for x < 0. Notice that x = 0 isnt a solution. If x > 0 then f'(x) > 0 which implies there can be at most one solution (if the function is always increasing it can intersect x axis at most once) By playing around you can see that 3³+3² = 36. (i first tried out 1, and then 2, and then 3...) Hence x³ = 3 <=> x= 3^⅓ is the only real solution.

When the discriminant is less than 0 it doesn’t mean it’s impossible it just means that there’s no real solutions. You still have imaginary solutions
