13log(25/4)-2log(4/5)+log(320/125)
Answer by Boreal(15235) (Show Source): You can put this solution on YOUR website!
13log(25/4)-2log(4/5)+log(320/125)=
13 log 25-13 log 4-2 log 4+2 log 5+log 320-log 125=
13 log 25-log 125-15 log 4+2 log 5+ log 320.;;- a log with a denominator will be + for the denominator
13log 25-log 5^3-15 log 4+2 log 5+log (5*l64)
13 log 5^2-3 log 5-15 log 4+2 log 5+log 5+log 64
26 log 5-3 log 5-15 log 4 + 3 log 5+ log 4^3
23 log 5-15 log 4+3 log 5+3 log 4
26 log 5-12 log 4
also 26 log 5-12 log 2^2=26 log 5-24 log 2.
===
check numerically 18.17-7.22=10.95
====
13 log 6.25=10.35
-2 log (0.8)=+0.19
+log(320/125)=0.41
These add to 10.95
