Answer:
11.776
Step-by -step Step-by-step explanation:
Here we are given a equation which is ,
And we would like to solve this using logarithms , so firstly add 8 on both sides , we get ;
Simplify,
Now take log to the base 10 on both sides ,
Recall that
.So ;
Again recall that
.So ; here
becomes 1 .
And the value of log 59.7 = 1.7759 . So on substituting this value , we have ;
Add 10 to both sides ;
Simplify,
And we are done !
