3^x=9x
3^x/x=9
3^3/3=27/3=9
x=3

Thanks for showing where you convert BOTH sides to a W function. That was cool.

I'm glad you found that part interesting! 🔥The Lambert W function is a powerful tool! 💯

3^(3-2)=3 x=3

Thanks but the second solution comes out of the blue...

[@RealQinnMalloryu4]

3^(x)^2 ➖ (2)^2=3^{x^2 ➖ 4}=3^{x^0 +x^0 ➖ }=3^x^1 = 3 (x ➖ 3x+3).

x = -W(-ln(3)/9)/ln(3)

It’s in my head.
