[x]W = P[X]U

Step-by-step explanation:

In this context [x]U means the coordinate vector of vector x in the basis U. We are given that P has the coordinates of the vectors of basis U in the basis W. This means, that P translates the coordinates in U basis to the coordinates of a vector in the W basis. So, given a vector [x]U (coordinates in the U basis) then, by multiplying by P, we get the coordinates of x in the W basis. That is

[x]W = P[X]U.
