Interesante video gracias por compartir la solución de la ecuacion exponencial. 😊❤😊.

18=16+2=4^2+√4 ,x=2 or 1/2 since 1 (1/2)=2

[@rajashashankgutta4334]

X is 2. Intuition

[@nasrullahhusnan2289]

4^x+4^(1/x)=18
=4²+4^½
Therefore x=2
Algebraicly take modulo 3:
[mod(4,3)]^x+[mod(4,3)]^(1/x)=0
1^x+1^(1/x)=0
1^(1/x) is the xth root of 1
1^(1/x)=-1 --> 1/x=½
Therefore x=2

Let us -> Let's

[@wasimvillidad3000]

x > 0, AM/GM theorem gives a minimum when x = 1, f(x) = 8.

[@Quest3669]

16+2= 18

[@barackfrans6777]

This is what I used to solve the equation

[@wryanihad]

Can we put 4^x=y
Then y+1/y=18
But.in the end we have x≈2.08
How that

[@StaR-uw3dc]

If y=4^x then 1/y=1/(4^x)=4^(-x)
