Location: Chapter 19, solution to Problem 5

It is

The first and last expressions in the solution read:

We can take \(C^*\) to be \(Q_1C\), because ...

...

In terms of \(C\) and \(Q_1\), \(B=(Q_1C)Q_1\).

It should become

We can take \(C^*\) to be \(C(Q_1C)\), because ...

...

In terms of \(C\) and \(Q_1\), \(B=C(Q_1C)Q_1\).

Short explanation

The need for a Cardinal bird at the beginning of the expression is made clear by the calculation given in the solution itself.
