`3log_(5)a+4log_(5)b-2log_(5)c`     (given)

`=log_(5)a^3+log_(5)b^4-log_(5)c^2`    (`n log_(b)m=log_(b)m^n` )

`=log_(5)(a^3*b^4)-log_(5)c^2`     (`log_(b)m+log_(b)n=log_(b)mn` )

`=log_(5)((a^3b^4)/c^2)`       (`log_(b)m-log_(b)n=log_(b)m/n` )

Hence the required answer is `log_(5)((a^3b^4)/c^2)` .
