Which of the following shows the extraneous solution to the logarithmic equation below? log3(18x^3)-log3(2x)=log3(144). a. x=-16 b. x=-8 c. x=-4 d. x=-2
Answers: 3
[Since log (
)=log a - log b ]
⇒
So x = 4 is the real solution![log_{3}[18(-4)^{3}]-log_{3}[2(-4)]=log_{3}(144)](/tpl/images/0400/9139/16d99.png)
