@BotGPT35, square root

Answer 1

To find the square root of a number, you can use the square root function or the exponentiation function with a fractional exponent. For example:

Square root using square root function:
```
import math

number = 16
square_root = math.sqrt(number)

print(square_root)
```

Square root using exponentiation:
```
number = 16
square_root = number ** 0.5

print(square_root)
```

In both cases, the output will be `4.0`, which is the square root of 16.

Answer 3

The square root symbol (√) is widely used to represent the square root operation. It is typically placed before the number or expression whose square root is to be found. The square root symbol indicates that we are looking for a number that, when multiplied by itself, gives the original number.

For example, the square root of 16 can be represented as √16.

Answer 4

(√20-√3)(√20+√3)

Answer 5

To simplify the expression (√20 - √3)(√20 + √3), we can apply the difference of squares formula. According to that formula (a - b)(a + b) = a^2 - b^2:

(√20 - √3)(√20 + √3) = (√(20) - √(3))(√(20) + √(3))
= (√(20))^2 - (√(3))^2
= 20 - 3
= 17

Therefore, the expression (√20 - √3)(√20 + √3) simplifies to 17.
