(12)

we are given


log_2(9x)

we can also write it as


log_2(9x)=log_2(9*x)

now, we can use property of log


log_2(9x)=log_2(9)+log_2(x)...........Answer

(13)


log_3((x^4y^8)/(2) )

we can use property of log


log((a)/(b))=log(a)-log(b)


log_3((x^4y^8)/(2) )=log_3(x^4y^8)-log_3(2)

we can use property of log


log(a*b)=log(a)+log(b)


log_3((x^4y^8)/(2) )=log_3(x^4)+log_3(y^8)-log_3(2)


log(a^n)=n*log(a)


log_3((x^4y^8)/(2) )=4log_3(x)+8log_3(y)-log_3(2)...........Answer

(14)


log_2(11)-log_2(z)

we can use property of log


log((a)/(b))=log(a)-log(b)

we get


log_2(11)-log_2(z)=log_2((11)/(z)).............Answer
