Question

find the value of
a. 3log(X+3)=log27
b.log^18 base 12+log^8 base12

Answer 1

Answer:

a. 3log(X+3)=log27

=>3log(X+3)=log3^3

=>3log(X+3)=3log3

=>log(X+3)=log3

=>X+3=3

=>x=0

b.log^18 base 12+log^8 base12

=>log^18*8 base 12

=>log^144 base 12

=>log^12^2 base 12

=>2log^12 base12

=>2

Answer 2

Answer:

Step-by-step explanation:

(a ) 3log(X+3)=log27

log(x+3)^3=log 3^3

(x+3)^3=3^3

powers are same so bases will be equal

x+3=3

x=3-3=0

part (b) is not clear
