Jeffrey left 4/7 of his wife and 1/4 of the remainder to his granddaughter. The part of his estate that is not accounted for,given as a factor isShow that in the definition of a vector space V the condition about
existence of additive inverse can be replaced with the condition:
0v = v, for all v is the element of V .
Here the 0 on the left side of the equation is the scalar 0, and on right side of
the equation is the additive identity of V .
