If loga and logb are the roots of the equation  mx^2 +nx+s=0, fimd in terms of m, n and  s the value of logab.

$$\mathrm{If}\:\mathrm{loga}\:\mathrm{and}\:\mathrm{logb}\:\mathrm{are}\:\mathrm{the}\:\mathrm{roots}\:\mathrm{of}\:\mathrm{the}\:\mathrm{equation} \\ $$$$\mathrm{mx}^{\mathrm{2}} +\mathrm{nx}+\mathrm{s}=\mathrm{0},\:\mathrm{fimd}\:\mathrm{in}\:\mathrm{terms}\:\mathrm{of}\:\mathrm{m},\:\mathrm{n}\:\mathrm{and} \\ $$$$\mathrm{s}\:\mathrm{the}\:\mathrm{value}\:\mathrm{of}\:\mathrm{logab}. \\ $$

log a +log b =−(n/m)  log (ab) =−(n/m)

$$\mathrm{log}\:{a}\:+\mathrm{log}\:{b}\:=−\frac{{n}}{{m}} \\ $$$$\mathrm{log}\:\left({ab}\right)\:=−\frac{{n}}{{m}} \\ $$
