You will get both of the fractions over the same denominator, so it will be 27/63 and 56/63, then you will add the two numerators, so it will then come out to 83/63, and you will then simplify that by subtracting 63 from 83, and will get 1 20/63
This is assuming you mean an object weights 38% less on mars then earth, if its the other way around(they weight 38% more on mars then earth) it would be,
F ( x ) = 6^(x+1) y = 6^(x+1) The inverse is: And when you plug in the values: x = 1, y = - 1: - 1 = log 1 - 1 - 1 = 0 - 1 - 1 = - 1 so the answer is: ( 1, - 1 )
