10 is greater than square root 20
√20 = √(2 x 10) = √2 x √10
10 = √10 x √10
√10 > √2 → 10 > √20
Equal, because the square root of 100 is 10, and 20 halves is also 10.
10 squared is 100. 20 squared is 400. 225 is between 100 and 400. Its square root will be between 10 and 20.
There is no square root of -75. If it's 75, that is 5 square root 3.
It is in between because it is 15
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
