The part we don't understand is: If you need to evaluate it, then why do we need to solve it ?
Here's a suggestion on how to go about it:
log8(0.51/3) = 1/3 log8(0.5)
To find log8(0.5) : let's call it 'Q'
8Q = 0.5
Q log(8) = log(0.5)
Q = log(0.5) / log(8)
Now you can find 'Q', and then 1/3 of Q is the answer to your original question.
The actual calculations to get a logarithm are quite complicated; in most cases you are better off if you look the logarithm up in tables, or use a scientific calculator.

There is nothing to solve because there is no = sign.

Evaluate is just the big scary word for solve it, seriously couldn't they just say solve?
It means to solve the problem.
Solve: Find a definite answer to X or Y or whatever. Evaluate: Find out a definite answer to the equation. Simplify: No definite answer. To evaluate usually implies plugging in the values for the variables. i.e. Evaluate 3x²+2 when x=5. The value of the expression (or its evaluation) is 77 ■
Algorithms are basically sequences of instructions to solve a problem or to perform a calculation. A logarithm is a specific mathematical concept. For more information on each, look at the sites listed below: Algorithms: http://en.wikipedia.org/wiki/Algorithm Logarithms: http://en.wikipedia.org/wiki/Logarithm

logb x = a According to the definition of the logarithm, a is the number that you have to exponentiate b with to get x as a result. Therefore: ba = x
