### Question 1

What is x if log_{x}(y) = 5 and log_{2}(x) = 3?

### Question 2

Which of these is correct?

**A**

$\text"log"(1 + 2 + 3)$ = $\text"log"(1 × 2 × 3)$.

**B**

$\text"log"_4(4)$ = 4.

**C**

$\text"log"_6(6)$ = 36.

**D**

$\text"log"_8(1)$ = 8.

**Soln.**

**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 m^{p} = n. We can see that none of the other options makes it correct.

### Question 3

Let us suppose that $\text"log"_3(4)$ = 4, then what is $\text"log"_4(3)$?

### Question 4

If log(343) = 3, what is log(49)?

### Question 5

What is x if log_{x}(y) = 5 and log_{2}(x) = 3?
