architaa:
as per i know log(x/y) = log x –log y and not log x + log y.
please mark me brainliest
why?

log dy/dx
log dy – log dx {log(x/y)=logx–logy}
log d + log y –(log d + log y){log(xy)=logx+logy}
log d + log y – log d – log y
log dy – log dx {log(x/y)=logx–logy}
log d + log y –(log d + log y){log(xy)=logx+logy}
log d + log y – log d – log y
this is a problem of derivative
