Suppose that u=log10(4) and v=log10(5). Find possible formulas for the following expressions in terms of u and/or v. Your answers should NOT involve any log 's.

I'm trying to find the log(250) and the log(0.064).

For log(0.064) I tried doing 0.08(u-v), but it wasn't right and I don't know what I did wrong.

For log(250) I tried the square root of u*v^3. It wasn't correct either. I don't know what I'm doing wrong. :(
