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
441 has two square roots; 21 or -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!!!
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
Square root of 9 is 3 and 3/21 = 1/7 in its simplest form
4.584/ 21 .00 00-1685 / 5 00-425908 / 75 00-7264336square root of 21 till 2 decimal places
The square root of 21 is 4.58257569495584.
The square root of 21 is 4.58257569495584.
4√21
4.6 is a better approximation to the square root of 21.
Expressed as a surd in its simplest form, the square root of 450 is equal to 15 sqrt(2). Rounded to two decimal places, this is equal to 21.21.
21
Root 64 is 8, if by root you mean the square root. Then the problem become -square root 84(6+8) which is the - square root of 84(14) But square root of 84 is 2(square root of 21) so the final answer comes from -2(square root 21)x14 which is -28square root (21)
