Best ResponseYou've already chosen the best response.0If the radius of the Milky Way Galaxy is about 50,000 (5x10^4) lightyears, and 1 lightyear is 5,878,630,000 (5.88x10^12), then: \[r=(5x10^{4} Lightyears)*(5.88x10^{12} miles/1 lightyear)\] then r=29.4x10^16 r=2.94x10^17 This is the answer

Best ResponseYou've already chosen the best response.0Lightyear in the numerator cancel with the numerator in the denominator, so you get the radius in miles

Best ResponseYou've already chosen the best response.0Multiplying 5x10^4 with 5.88x10^12. You have to multiply 5 and 5.88 first so you get 29.4. After that you have to multiply 10^4 and 10^12 = 10^4 (for this multiplication the base (10) remains and the exponents are added (4+12=16))

Best ResponseYou've already chosen the best response.0There is a mistake in the last post. Read this instead :) Multiplying 5x10^4 with 5.88x10^12. You have to multiply 5 and 5.88 first so you get 29.4. After that you have to multiply 10^4 and 10^12 = 10^16 (for this multiplication the base (10) remains and the exponents are added (4+12=16))
