Olympiad Mathematics | United Kingdom can you solve this?

[@sunnysharma5166]

After solving by simple method we get y=2

[@mathsatoka]

@sunnysharma5166 Good but that's not the only solution

[@sunnysharma5166]

@@mathsatoka there are 2 other complex solutions too

@@sunnysharma5166 exactly 💯

[@robertminor9297]

You can solve that one by just looking at it, 4x4x4=64 so y has to be 2

[@mathsatoka]

Yes but 2 is not the only solution

[@adgf1x]

y=2

[@mathsatoka]

That's not the only solution

@@mathsatoka i didnt say y=2 is only soln.might have pair of complex or irrational root.
