### Question 1

One-fifth of the square-root of which number is 0.6?

### Question 2

If x = 0.7727, then what is the value of $4x + √{16x^2 - 8x + 1}$?

### Question 3

What is the value of $√{7 + √1764}$?

### Question 4

If $4√3 + √27 = 12.12$, then what is the value of $√12 + 5√3$?

**A**

12.12.

**B**

12.00.

**C**

11.12.

**D**

12.96.

**Soln.**

**Ans: a**

The given expression can be rearranged like this: $4√3 + √{3^{2} × 3}$, which is same as $4√3 + 3√3$ which is same as $7√3 = 12.12$, from which we get $√3 = 1.73$. Next we can see that $√12 + 5√3$ is same as $√{2^{2} × 3} + 5√3$, which is same as $7√3$, which gives $7 × 1.73$ = 12.12.

### Question 5

What is the value of $√{3 + √1089}$?
