## Is 13 a rational or irrational number?

13 is a rational number. A rational number is any number that is damaging, positive or zero, and that may be written as a fraction.

**How do you remedy root 13?**

Square Root of 13 By Long Division Step 1: Group the digits into pairs from proper to left through placing a bar over it. Step 2: Find the most important number such that whilst you multiply it with itself, the product is less than or equivalent to 13. We know that 3 × 3 is 9 and is less than 13. Now allow us to divide 13 ÷ 3.

**How do you draw a Three on a number line?**

Now, once more draw a perpendicular at point B of duration BC= 1 unit and join the points O and C. Again through pythagoras theorem we get OC = root 3. Then by compus taking radius =OC, draw an arc in order that it cuts the number line at D. Then the gap OD would be the square root of 3.

### How do you represent root 7 on a number line?

With O as centre and radius BH, mark draw an arc and let it intersect the certain x-axis at M. M represents √7 at the number line. Hence √7 is represented at the number line.

**How do I make root 11?**

To find the square root of 11, use the lengthy division technique to get the approximate value. Therefore, √11 = 3. Register at BYJU’S to be informed other attention-grabbing mathematical concepts.

**How do you root Four on a number line?**

- Draw a no. line and take B at Zero and C at 1 i.e. take BC = 1 units with B at 0.
- Draw AC perpendicular to BC with duration 1 devices .
- Join AB and use Pythagoras theorem to seek out the length of AB which shall be ✓2.
- Keep pointer of compass at B and taking radius as BA draw an arc cutting the number line in point D. AB = BD =✓2.

## How do you draw a square root of a spiral?

Ex 1.2, 4 – Chapter 1 Class 9 Number Systems

- Mark a center level O.
- From point O, draw a horizontal line OA of length 1 cm.
- From level A, draw a perpendicular line AB of period 1 cm.
- Join OB, right here OB = √2.
- Now, from level B, draw a line perpendicular to OB (Use set squares) of length 1 cm.
- Join OC, right here OC = √3.
