Question 1
Which of these is correct?
$\text"log"(1 + 2 + 3)$ = $\text"log"(1 × 2 × 3)$.
$\text"log"_8(8)$ = 8.
$\text"log"_4(4)$ = 16.
$\text"log"_3(1)$ = 3.
Ans: a
Speaking factually, log(m + n + p) = log(m × n × p) is possible only if m × n × p = m + n + p, hence the answer, because 1 × 2 × 3 = 1 + 2 + 3. Expressions of the form $\text"log"_m(n) = p$ are same as mp = n. We can see that none of the other options makes it correct.
Question 2
What is the value of $\text"log"_4(√4)$?
Question 3
Let us suppose that log(4) = 2, then what is log($1/40$) if the base is 10?
Question 4
Suppose for the sake of this question that $\text"log"_4(5)$ = 10. Then what is $\text"log"_5(1024)$?
Question 5
What is the value of log(5) + log(6)?
