You take a guess as to an approximate square root, for example 2, which is the square root of 2. You divide 5 by 2, to get 2.5. The real square root will be between 2 and 2.5, so you take the average of these two (2.25). You divide 5 by 2.25 to get the next approximation. Repeat a few times, until you have the desired accuracy.
No, an irrational number is, in simple terms, a number that keeps repeating. The square root of 4 is positive or negative 2, which does not repeat and is therefore rational.

2 square root 2
the square root of 4 is 2 square root 2
The square root of the square root of 2
An irrational number, for example pi or e or the square root of 2

2 square root 2
square root 2 times square root 3 times square root 8
The square root of 2 plus the square root of 2 is equal to twice the square root of 2, therefore the correct answer is: 2(√2) or √8
4
the square root of 4 is 2 square root 2
2 is the same as the square root of 4. Square root of 4 multiplied by square root of 2 is equal to the square root of 8.
The square root of two times the square root of two equals two
