Square roots that are not the all-zeros matrix come in pairs: if R is a square root of M, then −R is also a square root of M, since (−R)(−R) = (−1)(−1)(RR) = R 2 = M. A 2×2 matrix with two distinct nonzero eigenvalues has four square roots. A positive-definite matrix has precisely one positive-definite square root.

For example, moving from a 2,500-square-foot house to a 1,500-square-foot townhome could help you reduce your property taxes, utilities and maintenance costs. However, remember that downsizing ...
In architecture, construction, and real estate, floor area, floor space, or floorspace is the area (measured in square metres or square feet) taken up by a building or part of it. The ways of defining "floor area" depend on what factors of the building should or should not be included, such as external walls, internal walls, corridors, lift ...
The fully automated facility would produce track slabs for 116 km (72 mi) of the double-line high-speed rail track for the corridor. The facility, spanning an area of 100,000 square metres, will produce 45,000 precast track slabs for the project. [173] 91 km (57 mi) of viaduct were completed at a rate of 2 km (1.2 mi) of viaducts per week.
The square root of 2 (approximately 1.4142) is the positive real number that, when multiplied by itself or squared, equals the number 2.
