- 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.
The square root of 400 is 20, and the square root of 450 is approximately 21.21. Therefore, the square number between 400 and 450 is 441, which is the square of 21.
Well, honey, to find the side length of a square with an area of 400 cm², you take the square root of the area. So, the square root of 400 is 20. Therefore, the side length of the square is 20 cm. Hope that clears things up for ya!
10 squared is 100. 20 squared is 400. 225 is between 100 and 400. Its square root will be between 10 and 20.
400 - 190 = 210
400 - 30 = 370
The square root of 400 is 20, as 20 multiplied by 20 equals 400. The square root of 196 is 14, as 14 multiplied by 14 equals 196. Therefore, the expression simplifies to 20 - 14, which equals 6.
sqrt(-400) => sqrt(400 X -1) => sqrt(400) X sqrt(-1) => +/- 20 X 'i' (NB Small/lower case 'i' is the symbol for square root of '-1'. So the answer is +/-20i NB Mathemticians for centuries have pondered over a solution for the square root of '-1'. If you know the answer let the mathemtical world. know!!!!!!
sqrt(400) = sqrt(20 x 20) sqrt(400) = 20
The square root of 400 is 20.
Neither because the square root of 400 is 20
20 and -20
The square root of 4,001,616 is approximately 2000.404
The square root of 400 is 20, which is a rational number because it can be expressed as the fraction 20/1. Therefore, 400's square root is not an irrational number; it is a whole number.
it is 400
20
The square root of 400 is 20, and the square root of 450 is approximately 21.21. Therefore, the square number between 400 and 450 is 441, which is the square of 21.
The square root of 400 is rational because it can be expressed as a whole number. Specifically, the square root of 400 is 20, which is a rational number since it can be represented as a fraction (20/1). Therefore, it is not an irrational number.
