Thank you!

log_10(15)=log(15)/log(10) log(10)=1 log(10)=log(5*2)=log(5)+log(2)=1 log(2)=x so replacing it is log(5)=1-x then in the first part log(15)=log(3*5)=log(3)+log(5)=y+1-x so log_(10)=log(15)/log(10)=y+1-x/1 so finally it equals log_10(15)=y+1-x hope you
Thank you for the solution! I think the mistake is at the calculations of finding dy/dt, I think it is 0.72. Maybe I am wrong but one more time I thank you in advance.
