### Question 1

What is x if log_{x}$(4/7)$ = 1?

### Question 2

Which of these is correct?

**A**

$\text"log"_4(1)$ = 0.

**B**

$\text"log"_6(6)$ = 6.

**C**

$\text"log"_2(2)$ = 4.

**D**

$\text"log"(4 + 6 + 2)$ = $\text"log"(48)$.

**Soln.**

**Ans: a**

Speaking factually, $\text"log"_m(1)$ = 0 because m^{0} = 1 always, hence the answer. Expressions of the form $\text"log"_m(n) = p$ are same as m^{p} = 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 the value of $\text"log"_2(√2)$?

### Question 4

Suppose for the sake of this question that $\text"log"_2(7)$ = 14. Then what is $\text"log"_7(128)$?

### Question 5

What is x if log_{x}(y) = 7 and log_{2}(x) = 2?
