It’s the first one because when you have a line under the inequality it’s always going to be a solid line and since it’s negative it’s shaded below.
Multiply 6 ten time by itself
6*6*6*6*6*6*6*6*6*6 which = 60,466,176
and 6 by itself four times
6*6*6*6 which = 1,296
Then divide 60,466,176 by 1,296
Answer: 46,656
