You can put this solution on YOUR website! Evaluate the following expression without using a calculator.
log base 7 of root 7 = x
I changed the form of the equation to 7^x=sqrt(7)
----
OK, then 7^x = 7^(1/2)
Finally, x = 1/2
------
Another way to do it:
log7(sqrt(7)) = x
x = log7(7^(1/2))
---
x = 1/2*log7(7)
x = (1/2)*1
x = 1/2
