5*sqrt(400) = 100
The square root of 400 is 20.
Neither because the square root of 400 is 20
sqrt(400) = sqrt(20 x 20) sqrt(400) = 20
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!!!!!!
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.
The square root of 400 is 20.
Square root 400 - square root 196 = 6
Neither because the square root of 400 is 20
20 and -20
sqrt(400) = sqrt(20 x 20) sqrt(400) = 20
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!!!!!!
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.
2 x 2 x 5 = 20
22 x 5 = 20
