Reading #15 Economics question long, question, correct, example

I’m on page 615 (Reading #15, example number 9 in CFAI text).  In the second question, it asks us to calculate the long term sustainable earnings growth rate using data from ‘95-‘08.  I am not understanding how they are getting 7.5% and 4.6% (China and India’s long-term growth of labor productivity).  There’s a footnote at the end of the question saying “calculated as gerometric mean growth rate using data from 1995-2005 and 2005-2008.  Can anyone show me the correct calculation to get those numbers?

CPK sounds right

1995-2005 period : ( value at end / value at beginning ) ^ (1/9) - 1?
and
2005-2008 period: ( value at end / value at beginning ) ^ (1/3) - 1?
The readings have changed - and I do not have access to the tables above … but this  is what I think it would be.
