Should the EPR calculation on page 154 of the CTS-D exam guide be changed to look like my edit in the image?
I added the carat symbol to make the results match the diagram with Biamp's online calculator on page 156.
Or is this an unfamiliar way to express exponents? Parenthesis denote multiplication of a cordoned-off group of ordered operations to me, anyway.

You are correct, the equation as published is incorrect. In the original chapter text the equation reads correctly. However, I asked the layout people to increase the size of the typeface of the [bracketed] section of the equation to make it more legible. In the process, the alignment of the text was compromised, an issue that was unfortunately missed by myself, the proofreaders, production editor and technical editors, until the book was already in print. This error was noted in April 2023 and has been marked down for correction in any future reprints. As I'm not sure how to post an image into a comment, I'm sorry that I can't show you the original correct version. Perhaps I'll post it as a separate thread.
