Question

Q. If log4 (x² + x)- log4(x+1)=1 then the value of x is ​

Answer 1

Step-by-step explanation:

= log4 (x² + x)- log4 (x+1)=1

We can write it as;

= log4 {(x² + x)/(x+1)} =1; { from the rule : logb a - logb c = logb (a/c) }

= log4 {x(x + 1)/(x+1)} =1;

= log4 {x} =1;

Thus, x = 4.

That's all.
