Can you simplify the square root of 7?
Since 7 is a prime number, it has no square factors and its square root cannot be simplified. It is an irrational number, so cannot be exactly represented by pq for any integers p,q . with n=7 , p=8 and q=3 .
What is square rooting?
A square root of a number is a value that, when multiplied by itself, gives the number. Example: 4 × 4 = 16, so a square root of 16 is 4. Note that (−4) × (−4) = 16 too, so −4 is also a square root of 16. The symbol is √ which always means the positive square root. Example: √36 = 6 (because 6 x 6 = 36)

Is the square root of 8 a real number?
Is square root of 8 a real number? Yes, square root of 8 is a real number.
How do you simplify square root 8?
- Simplifying the value of root 8 is simple and easy to follow.
- For simplifying the root 8 value, first, write √8 as 22 x 2.
- Taking the whole root of the value 22 x 2, you get √4 x √2.
- Now, take out 4 from the radical since √4 value is 2.
- After doing this you will get 2√2.
- Hence, the exact value of √8 is 2√2.
How do you simplify square root equations?
To simplify an expression containing a square root, we find the factors of the number and group them into pairs. For example, a number 16 has 4 copies of factors, so we take a number two from each pair and put it in-front of the radical, which is finally dropped i.e. √16 = √(2 x 2 x 2 x 2) = 4.
