Homework Statement



This isn't really a homework problem, as the entire solution is laid out in the text. My question is in regards to a possible typo, which I have highlighted in blue in the given picture.
Usually I don't like to second guess the text, but this one has been absolutely plagued by typos and I usually have to go to the professor to see if it really is a typo or if I missed something.

Mine as well. The "7" and the "49" are wrong.

Ok thank you fresh. Really hate having to deal with typos, but I'm sure they're hard to avoid when writing an 800 page book of numbers.
