sqrt(21) cannot be simplified.
if you mean what is square root of 200 in its simplest radical form its 10*21/2
The square root of 21 is 4.58257569495584.
21The square root of 441 is 21
It isn't. √22 + √23 = 9.486. √21 + √24 =9.482. its not that its more than that!!! its..... NOTHING!!! you got that??? NOTHING at all!!!
441 has two square roots; 21 or -21.
5 times the square root of 21
if you mean what is square root of 200 in its simplest radical form its 10*21/2
First note that 84=4x21 and 4 is a perfect square. So square root of (84)=square root (4x21)=Square root (4) Square root (21)= 2 multiplied by the square root of 21. You can also write this using rational exponents, but this is not in radical form. It is an equivalent expression, however. 2 x (21)1/2
The square root of 84 is approximately 9.165. This value can be simplified to (2\sqrt{21}) when expressed in its simplest radical form.
Square root of 9 is 3 and 3/21 = 1/7 in its simplest form

Yes, the square root of 21 is irrational. This is because 21 is not a perfect square, and the square root of any non-perfect square is irrational. Additionally, the square root of 21 cannot be expressed as a fraction of two integers.
4.6 is a better approximation to the square root of 21.
