I think that the answer is 2, because if you multiply two by each factor in the original photograph then you get the size of the new photograph.
law's of exponents
e^(x-5)*e^(3x+8) = 19
e^(x-5+3x+8) = 19
e^(4x+3) = 19
take the natural log, which is base "e" of both sides.
ln[e^(4x+3)] = ln[19]
4x +3 = ln[19]
4x = ln[19] - 3
x = (ln[19] - 3) / 4
x = -0.0139
Answer:18 million and 300000
Step-by-step explanation:
Since light travels 180 million KM in 10 min, it would travel 180 million/10 in one minute. Thus, we get 18 million. As we know, there are 60 seconds in a min. Thus, there are 60*10=600 seconds in 10 minutes. Thus, 180 million/600 gives 300000
If I'm correct the answer is 512 but that's if I'm correct. :P
