1. I need some help understanding ratios between 2 numbers/quantities og exponents: 2.Here is the problem, When you take the ratio between 100grams and 1000grams it is 100g/1000g = 0,10 and you can convert this to kilos 0,1kg/1kg = 0,10 and the ratio stays intact, that makes sense. But let's say the relationship between the mass of the egg a bird lays and the mass of the bird is given by M_egg = c*M_bird^(0.77). Then the constant c is a ratio betwen M_egg/M_bird^0,77. If the bird weighs 1.5kg and the egg weighs 0,070kg, then I get two completely different results if I first calculate the ratio in grams and efter that in kg. Why is that? And how do you work around it? In grams M_egg/M_bird^077 = 0,070kg/1.5^(0,77)kg = 0.051 in kg M_egg/M_bird^077 = 70g/1500^(0,77)5 = 0.025 Is there some fundamental theory i need to understand about exponents that i missed out on?
