Super sir 👍

[@SALogics]

Very nice! ❤

[@فیروزاهنگری]

(-a)^1/a=4 , (-1/a)^-1/a=2^2 , -1/a=2 then a=-1/2

[@SALogics]

Very nice! ❤

[@sofianikolidou5640]

Super🎉🎉

[@SALogics]

Thank you! ❤

[@nasrullahhusnan2289]

Note that a x=½ and hence a=-½

[@SALogics]

Very nice! ❤

[@LITHICKROSHANMS-gw2lx]

Super 👍🏻

[@KulamaniBehera-y7h]

Good example

[@SALogics]

Thank you so much! ❤

Faça a mudança de variável: (-1)/a = x.

[@ashwanibeohar8172]

Maths is for making things easy, not first create complex eqn from simple situation and then solve it.

[@SALogics]

This is just for learnig new techniques! ❤

[@giulio00010001]

Why you continue to repeat the left expression on the left side that is always the same?

[@SALogics]

Sorry for that! ❤

[@narsinhapotdar7215]

Good

[@SALogics]

Thank you so much! ❤

[@SGuerra]

Parabéns pela questão. É possível obter a solução sem fazer uso da função W. Brasil - Outubro de 2024.

[@SALogics]

muito obrigado! você pode compartilhar esse truque?

[@SGuerra]

​@@SALogicsfaça (-1)/a = x.

Thank you so much! ❤

-1 ÷2 coulldn't degree of radical. İt is must be natural

[@SALogics]

Noted with thanks! ❤

[@gilmartrevisan]

Ahhh, gosh I solved it using product log But your solution is better a = -e^(-W(ln4))

[@SALogics]

Thank you so much! ❤

[@nancymatro8029]

I got the same wrong answer as you. According to Wolfram Alpha, -e^(-W(ln4)) does not equal -1/2, which is the correct answer. So, the fact that SALogics thanked you, means that he doesn't know English.

[@nancymatro8029]

@@SALogics why did you thank him for getting the wrong answer, instead of explaining what he did wrong?

[@trojanleo123]

a = -1/2

[@SALogics]

Yes, you are right ❤

[@TWJRPGGamming]

-1/2

[@SALogics]

Yes, you are right ❤

[@次野先生]

암산으로 -1/2

[@SALogics]

Yes, you are right! ❤
