raise 6 to the 7th power, then find the difference of the result and c

Question

write an expression, MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM

Answer 1

6^7 -c

= 279,936 - c

c = 100 as a Roman numeral

or

c= speed of light = 2.998 x 10^8 m/s

if former then 279936 -c = 279836

if latter then 279936-c = 279936- 2.998x10^8 = 379,936 - 399800000 =400,179,936 = about 400 million meters per second
