Let V = R be the set of all reals with the operations (a) u + v = uv and (b) a • u = au. Determine whether V is a vector space or not? Hint: check to see if at least one of the 2 closures or one of the 8 properties fails, then V is NOT a vector space!

V is not a vector space

Step-by-step explanation:

Given: V = R be the set of all reals with the operations (a) u + v = uv and (b) a • u = au.

To find: whether V is a vector space or not

Solution:

A vector is a quantity that has both magnitude and direction.

A vector space is a set of all vectors.

According to properties of vector space,

there is a vector 0 (zero vector) such that

According to the given condition: u + v = uv

So, there does not exists a zero vector in V  such that

Hence, V is not a vector space.

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
