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

Square root of 400 simplified is 20.

The square root of 400 is 20.

Neither because the square root of 400 is 20

The square root of 4,001,616 is approximately 2000.404

it is 400

20

20i, where "i" is the imaginary unit.

+/- 20i where i is the imaginary square root of -1.

5*sqrt(400) = 100

20

Yes, they are.

- (400^.5) = -(20) = -20 you just do the square root of the number, and attach the negative in front. and if you ever include the negative inside the square root, you'd have to deal with i, which is an imaginary number that signifies the square root of negative 1.

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.

- sqrt(1) - sqrt(-400) = -1 - 20i, where "i" is the imaginary unit.- sqrt(1) - sqrt(-400) = -1 - 20i, where "i" is the imaginary unit.- sqrt(1) - sqrt(-400) = -1 - 20i, where "i" is the imaginary unit.- sqrt(1) - sqrt(-400) = -1 - 20i, where "i" is the imaginary unit.

By realizing that 20 x 20 = 400

20 and -20

Yes, they are.

It is rational.

20 is one of the two square roots of 400.

√400 = 20, -20

The square root of 400, also known as 20.

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

There are two answers: 20 and -20
