Question 1
Which of these is correct?
$\text"log"_2(1)$ = 0.
$\text"log"_7(7)$ = 7.
$\text"log"_8(8)$ = 64.
$\text"log"(2 + 7 + 8)$ = $\text"log"(112)$.
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.
Question 2
What is the value of $\text"log"_4(√4)$?
Question 3
Which of these is correct?
$\text"log"_6(8)$ = $1/{\text"log"_8(6)}$.
$\text"log"_8(8)$ = 8.
$\text"log"_4(4)$ = 16.
$\text"log"(6 + 8 + 4)$ = $\text"log"(192)$.
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 4
What is log$4/3$ + log$3/4$?
Question 5
Let us suppose that $\text"log"_2(3)$ = 3, then what is $\text"log"_3(2)$?
