The galaxy NGC 4414 is moving away from us at 7.16x105 m/s?
The galaxy NGC 4414 is moving away from
us at 7.16x105 m/s. By how much will the
frequency of the 6.91 x1 014 Hz hydrogen line
be shifted in the galaxy's spectrum?

frequency shift is approximately equal to df= v/lambda when v is very much less than c.
You have df= v/lambda=f v/c= 7.16x105
6.91 x1 0^14 Hz *7.16*10^5/3*10^8=16.5*10^11=1.65*10^12 Hz

your numbers are meaningless, please learn proper notation.

no. please learn how to spell. 7.16x10⁵ m/s or 7.16x10^5 m/s.
