Log(8)+3/5Log(14) - 3/5Log(7)+Log(1/(2^{13/5}))
i got log (8*14^{3/5}) / Log (7^{3/5 }*1/(2^{13/5 })) = Log(2)
Just wondering if you can solve this without using a calculator since my exams forbid calculators.

This is a simple exercise in properties of the exponential. Do you not know that and ?
[QUOTE=chewydrop;830170]Log(8)+3/5Log(14) - 3/5Log(7)+Log(1/(2^{13/5}))[/tex]
so [tex]log(8)= 3 log(2). so . so
So you have 3 log(2)+ (3/5)log(2)+ (3/5)log(7)- (3/5)log(7)- 13/5 log(2)
Now, it's just arithmetic.
i got log (8*14^{3/5}) / Log (7^{3/5 }*1/(2^{13/5 })) = Log(2)
