You're the best!
Very effective method of teaching She has a command over her Subject knowledge.
27^(2/3)+27^(2/3)+27^(2/3)=27 x=2/3=0.6 recurring It’s in my head.
❤
Thanks
A more simple resolution:26^x=yy+y+y=273y=27y=927^x=9(3^3)^x=3^23^3x=3^23x=2X=2/3
Nice
Method 1 : ( 27^x ) = 9 => log ( 27^x ) = log 9 => x log 27 = log 9 => x = log 9 / log 27 = log 3^2 / log 3^3 = 2 log 3 / 3 log 3 => x = 2/3
Thank you beautiful tutor. Why do you go with the long method first.
You’re welcome 😊
Just playing with numbers🤣
the 2nd method is this first method came on my mind - it’s straight forward ❤no reason to use the 1st complicated method 😂
Ok. Thank you
Genious minds are meteors made to burn to enlight their century 🙏🙏🙏🙏🙏🙏🙏🙏.
X=2/3
27^x=27/3 ,; i,e 27^x=9 ; i,e 3^(3x)= 3^2 ; 3x=2 ; i,e x=2/3
Do not complicate things just put 27 power of x = y and solve it simply. It is not Olympiad.😊
27^x + 27^x + 27^x = 27 => 3 ( 27^x ) = 27 => 27^x = 9 => 3^3x = 3^2 => 3x = 2 => x = 2/3
Sorry dear but the answer is X=2/3 by inspection because 27 to the power 2/3 is the cubed root of 27 which is 3 the square it 3 squared is 9 so it is 9+9+9=27 simple!
Too long lve got it!

A more simple resolution:
26^x=y
y+y+y=27
3y=27
y=9
27^x=9
(3^3)^x=3^2
3^3x=3^2
3x=2
X=2/3
Nice
