The dwarf planet Eris has no atmosphere and has been easier to measure than Pluto. At its largest, the diameter of Eris is 2,338 km. Using 2376.6 km as the diameter of Pluto. As a
percent difference, how much larger is Pluto than Eris?

1.6%

Step-by-step explanation:

2376/2338= 1.016

1.016-1 = .016 * 100

step-by-step explanation:

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
