sqrt(20)
= 4.472135955
At nine places and looking very irrational to me!
42 is 16, less than 20 52 is 25, more than 20. so, 20 is not a perfect square, and does not have an integral square root. But, the square root of any integer is either an integer itself, or irrational. So, square root 20 is irrational
The square root of 20 is an irrational number
The square root of 94 is an irrational number
The square root of 200 is irrational.
irrational
Irrational (and a multiple of i), as the square root of 255 is irrational.
The square root of 11 is an irrational number
The square root of 20 can be found using a calculator or by using the approximation method. The exact value is √20 ≈ 4.47.
If the positive square root (for example, square root of 2) is irrational, then the corresponding negative square root (for example, minus square root of 2) is also irrational.
It is a irrational number. Because the square root of every imperfect square is irrational number.
