Question 1
What is the value of log(6) + log(7)?
Question 2
Which of these is correct?
$\text"log"(1 + 2 + 3)$ = $\text"log"(1 × 2 × 3)$.
$\text"log"_4(4)$ = 4.
$\text"log"_6(6)$ = 36.
$\text"log"_8(1)$ = 8.
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 3
Let us suppose that $\text"log"_7(2)$ = 2, then what is $\text"log"_2(7)$?
Question 4
Which of these is correct?
$\text"log"_3(1)$ = 0.
$\text"log"_8(8)$ = 8.
$\text"log"_2(2)$ = 4.
$\text"log"(3 + 8 + 2)$ = $\text"log"(48)$.
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 5
Suppose for the sake of this question that $\text"log"_2(5)$ = 10. Then what is $\text"log"_5(32)$?
