log_{5}(5b^2c^4)= log_{5}  5+log_{5}  b^2+log_{5}  c^4=1+2log_{5}  b+4log_{5}  c

log_{5}  (125c^5 frac{2}{3} )=log_{5}  125+log_{5}  c^5+log_{5}   frac{2}{3} =3+5log_{5}  c+log_{5}  2-log_{5}  3

log_{5}  (a^325b sqrt{5} )=log_{5}  a^3+log_{5}  25+log_{5}  b+log_{5}   sqrt{5} =3log_{5}  a+2+log_{5}  b+ frac{1}{2} =3log_{5}a+log_{5}  b+2.5

log_{5}  (25 a^{-3} b^2c^4)=log_{5}  25+log_{5}   a^{-3} +log_{5}  b^2+log_{5}  c^4=2-3log_{5}  a+  +2log_{5}  b+4log_{5}  c
