 Homework Statement:

Because v<<c in this case, we can expand the denominator
(1 + x)^1 = 1  x + ... keeping only the lowest term in x
v/c. The above equation becomes...
 Relevant Equations:
 (1 + x)^1 = 1  x + ...
I am wondering if there is a typo in my textbook. Please see the attachment. The textbook says "...keeping only the lowest term in x = v/c." I am wondering if it should be "x = v/(nc)," as I circled in blue on the left side. It is a binomial expansion of the denominator. Shouldn't x be v/(nc) instead of v/c? The textbook says "...keeping only the lowest term in x = v/c." Thank you.
