Question 1
What is log$7$ + log$1/7$?
Question 2
What is x if logx$(3/5)$ = $1/2$?
Question 3
What is log$3/4$ + log$4/3$?
Question 4
What is the value of log(4) + log(5)?
Question 5
Which of these is correct?
$\text"log"_4(1)$ = 0.
$\text"log"_8(8)$ = 8.
$\text"log"_6(6)$ = 36.
$\text"log"(4 + 8 + 6)$ = $\text"log"(192)$.
Ans: a
Speaking factually, $\text"log"_m(1)$ = 0 because m0 = 1 always, 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.
