Differentiate y=log10(√(x-a)+√(x-b)

y=log10( xa+xb)

= loge( xa+xb) log10e

differentiating both sides with respect to x

dydx=log10eddxlog(xa+xb)

=log10e1xa+xbddx(xa+xb)

=log10e1xa+xb[ddxxa+ddxxb]

=log10e1xa+xb[ 12(xa)1/21ddx(xa)+ 12(xb)1/21ddx(xb)]

=log10e1xa+xb12[1xa1+1xb1]

=log10e2( xa+xb)[( xa+xb)xaxb]

=log10e2(xa)(xb)
