Expert Solution
Step 1

4 We have to prove that there does not exist a linear map T:R5R5such that rangeT=nullT.

We know that the range-nullity theorem is given by

RankT+nullityT=dimV, where Vis the vector space.

Here, V=R5

dimV=5

Let us suppose rangeT=nullT=m

m+m=52m=5m=52m=2.5

Which is not possible.

Hence, it contradict the statement rangeT=nullT=m.
