How do you determine if a set of vectors is a subspace?
In other words, to test if a set is a subspace of a Vector Space, you only need to check if it closed under addition and scalar multiplication. Easy! ex. Test whether or not the plane 2x + 4y + 3z = 0 is a subspace of R3.
How do I show a subspace?
1. Let V be a vector space over F, and let U be a subset of V . Then we call U a subspace of V if U is a vector space over F under the same operations that make V into a vector space over F. To check that a subset U of V is a subspace, it suffices to check only a few of the conditions of a vector space.
What is the value of x + y + z = 1?
There is no unique answer. The equation x + y + z = 1 describes a plane in 3-space, and x 2 + y 2 + z 2 = 1 describes a sphere. We are interested in points ( x, y, z) anywhere on the circle where they intersect, which is obviously the circle defined by the three points ( 1, 0, 0), ( 0, 1, 0), and ( 0, 0, 1).

How do you solve X³ = Y³ + Z³ using Fermat’s Last Theorem?
According to Fermat’s Last Theorem, there exists no integer (x,y,z) > 1 and n > 2 which satisfies the relation xⁿ + yⁿ = zⁿ. so the equation x³ = y³ + z³ will have no solutions in positive integers with (x,y,z) greater than 1. So the only possible triplets (x,y,z) are (1,0,1) and (1,1,0).
