please help me with this question

Recolll = [2, 3],2 = [I], 2], $1 = [3,0] and i3; = [3, 2], so thatB = {111,112} and C = {'51, E52} are bases of R2. Having found the transition matrix P03 in the previous question, now find the coordinates of the following vectors with respect to 0' (enter the coordinates as a vector in the form [1, 3]). The coordinotes of {:3 = 2.111 3&2 with respect to C are (13);; = The coordinates of {:3 : 3.1 + 2.17.; with respect to C are (113),; = The coordinates of 13 = 7.111 7.17.2 with respect to C are (13)
