Let V, W be finite dimensional vector spaces and T: V → W be a linear transformation. Let A = [T]½ and B= [T], where B, B' and Y, Y' are bases of V and W respectively. Let R be the RREF of A and R' be the RREF of B. (a) Prove that the number of leading ones in R is equal to the number of leading ones in R'. (b) Show by example, that R and R' need not be equal.
