Comment:
"log" means "exponent" or "power"
------------------
log27x=2/3
You are told "the exponent or power is 2/3"
You are also told that is 27 which has this exponent
Then you are told the result of applying that exponent of 27 is "x".
------------------
So the exponential form of your problem is:
27^(2/3) = x
To solve this problem rewrite 27 as 3^3 to get:
[3^3]^(2/3) = x
Multiply the exponents to get:
x = 3^2
Simplify to get:
x = 9
==============
Hope this helps.
Remember: when you see the word "log" think "exponent".
Cheers,
Stan H.
