Answer to part A: If the sun produces 3.9 (10^33) ergs or radiant energy for every second, then how much energy does the sun produce in 3.25 (10^3) seconds? Just multiply (3.25 [10^3]) (3.9[10^33]) = 1.2675 10^37 of ergs of radiation. 

Answer to part B: 1.435 10^3 mm is a reasonable answer because it is much smaller than 1.435 10^3.  

Answer to BONUS: 
(2^8 5^-5 19^0) ^-2 (5^-2 / 2^3) 2^28 <-- Start
(256  0.00032 1) ^-2 (0.04 / 8)  268435456 <-- Simplify
0.08192^-2 0.005 * 268435456 <-- Simplify the terms in parentheses.


Final Answer: 200000000

Whew! That was hard!
