It is 2*sqrt(5).

The sqare root of 20.

You can always add radicals, but you can't simplify unless the radicands have a common factor. For example, the square root of 20 plus the square root of 45 equals 2 times the square root of 5 plus 3 times the square root of 5, which is 5 times the square root of 5.

The square root of 20 is: ± 4.472136The square root of 20 is ± 4.472136 (to 7 sf).A square root of a number is the number that when multiplied by itself equals the given number.

The answer is 6 The square root of 9 is 3 times 20 equals 60 divided by 10 equals 6

3x^2=-20 so x^2=-20/3 this has no real roots but the plus of minus i(square root of 20/3) is a solution if we allow complex numbers.

Because the Square Root of negative 1 = i (The imaginary square root of negative 1.) and where if the square root of one number and of another number are multiplied together, the answer is equal to the square root of the two numbers combined. (Square root of 8 times the square root of 5 equals the square root of 40.) So... √(-20) =√20×√(-1) =√4×√5×i =2i(√5) The answer is 2i times the square root of 5. square root (-20) = square root (-1) x square root (20) square root (-20) = i x 4.47213595 square root (-20) = 4.47213595 i

There is no square root of -75. If it's 75, that is 5 square root 3.

square root of 20 = square root of 4X5=square root of 4 X square root of 5=2*square root of 5.

The square root of 75 is 8.66 and the square root of 20 is 4.47.

If it's just the square root of x, and that is over 20, you're looking for x=100. Here's why: 1/2 is one half. What number is 1/2 of 20? 10, right? What number has a square root that equals 10? 100! So~ the square root of 100 is 10. 10 out of 20 is equal to 1 out of 2.

The perpendicular distance from (2, 4) to the equation works out as the square root of 20 or 2 times the square root of 5

square root of 20 = square root of 4 * square root of 5. square root of 4 = 2, so your answer is 2 square root of 5.

10 - (5 x 2 x 2) + (16 x 4) + 20 + 1000 - 100 10 - 20 + 64 + 20 + 1000 - 100 All of that equals 974. You didn't indicate what the square root was of or how it applies.

Sqrt of 200+(6*20) = 134.1421356

1 plus 19 equals 20 2 plus 18 equals 20 3 plus 17 equals 20 4 plus 16 equals 20 5 plus 15 equals 20 6 plus 14 equals 20 7 plus 13 equals 20 8 plus 12 equals 20 9 plus 11 equals 20 10 plus 10 equals 20 1 times 20 equals 20 2 times 10 equals 20 4 times 5 equals 20

If you mean the square root is 20, the answer is 400. If you mean the square root of 20, the answer is about 4.47.

The square root of 410 equals 20.2485. 20.2485 is between the two integers, 20 and 21.

the square root of 20 in it's simplest form is ^2 square root of 5

The square root of 20 is an irrational number that can be expressed as 2 times square root of 5

The square root of 400 is 20. 20 times 20 is 400. * * * * * -20 is also a square root of 400.

sqrtx=20 to get rid of the square root you square both sides so sqrt(x)^2=x and (20)^2=400 x=400

Square root of 400 simplified is 20.
