Question 1
Suppose for the sake of this question that $\text"log"_3(2)$ = 4. Then what is $\text"log"_2(9)$?
Question 2
Let us suppose that $\text"log"_3(4)$ = 4, then what is $\text"log"_4(3)$?
Question 3
What is $1/{\text"log"_3(60)}$ + $1/{\text"log"_4(60)}$ + $1/{\text"log"_5(60)}$?
Question 4
Which of these is correct?
$\text"log"_6(2)$ = $1/{\text"log"_2(6)}$.
$\text"log"_2(2)$ = 2.
$\text"log"_4(4)$ = 16.
$\text"log"(6 + 2 + 4)$ = $\text"log"(48)$.
Ans: a
Speaking factually, $\text"log"_m(n)$ = $1/{\text"log"_n(m)}$, hence the answer. Expressions of the form $\text"log"_m(n) = p$ are same as mp = n. We can see that none of the options makes it correct. Also, log(m + n + p) = log(m × n × p) is possible only if m × n × p = m + n + p.
Question 5
Suppose for the sake of this question that $\text"log"_2(7)$ = 14. Then what is $\text"log"_7(128)$?
