If I counted the zeros correctly it would be 1 times 10 to the 60th power.
100,0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 pounds
(1 x 1063)+ (1 x 1059) = 1.0001 x 1063
'Tis a very large number; one best written in scientific notation. Just write "10", count the zeros, and put the result as an exponent. 10^60 = One novemdecillion
