U.S. Nominal GDP for the year 2010 was $14658 billion whereas in 2000 it was $9951 billion. The GDP deflator for 2000 (2010) was 88 (111) using 2005 as a
base year. Using the compound growth formula xt+n = xt(1 + g)^n (where xt is the value of the series at time t n is the number of years and g is the annual

numbers in
