Question 1
What is ${\text"log"(√7)}/{\text"log"(7)}$?
Question 2
Which of these is correct?
$\text"log"_8(7)$ = $1/{\text"log"_7(8)}$.
$\text"log"_7(7)$ = 7.
$\text"log"_4(4)$ = 16.
$\text"log"(8 + 7 + 4)$ = $\text"log"(224)$.
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 3
What is x if logx$(5/3)$ = $1/2$?
Question 4
What is log$7$ + log$1/7$?
Question 5
What is x if logx$(2/4)$ = $1/2$?
