Answer:

2/3

Step-by-step explanation:

[tex]log_{27}(9)[/tex]

Let x= [tex]log_{27}(9)[/tex]

Convert it into exponential form

 [tex]x= log_b(a)[/tex] can be written as [tex]b^x= a[/tex]

x= [tex]log_{27}(9)[/tex] can be written as [tex]{27}^x= 9[/tex]

27 is 3 times 3 times 3 . its 3^3

9 is 3 times 3 . its 3^2

[tex]{27}^x= 9[/tex]

[tex]{3^3}^x= 3^2[/tex]

[tex]{3}^{3x}= 3^2[/tex]

Base are same so we equate the exponents

[tex]3x= 2[/tex]

Divide both sides by 3

x= 2/3
