What is the square root of 121?10111213If x is a prime number, what the value of  will beRational NumberIrrational NumberInteger NumberWhole numberWhich of the following is a prime number?1246

Let's go through each question step by step.

### 1. What is the square root of 121?
- \( 10 \)
- \( 11 \)
- \( 12 \)
- \( 13 \)

#### Solution:
- The square root of \( 121 \) is \( 11 \), because \( 11 \times 11 = 121 \).

**Answer:** \( 11 \)

### 2. If \( x \) is a prime number, what will the value of \( x \) be?
- Rational Number
- Irrational Number
- Integer Number
- Whole number

#### Solution:
- A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. 
- Since prime numbers are natural numbers, they are also whole numbers, integers, and rational numbers.
- The value of \( x \) (a prime number) will be a **whole number** (which is also an integer and rational number).

**Answer:** Whole number (It can also be considered as an integer or rational number, but since the question likely expects a single answer, "Whole number" is a safe choice.)

### 3. Which of the following is a prime number?
- \( 1 \)
- \( 2 \)
- \( 4 \)
- \( 6 \)

#### Solution:
- \( 1 \) is not a prime number (it has only one divisor: 1).
- \( 2 \) is a prime number (it has exactly two distinct positive divisors: 1 and 2).
- \( 4 \) is not a prime number (it has three divisors: 1, 2, and 4).
- \( 6 \) is not a prime number (it has four divisors: 1, 2, 3, and 6).

**Answer:** \( 2 \) is a prime number.
