None of them? 6x3 is 18, 6x6x6 is 216, 6x6x6x6 is 1296, and 3x3x3x3x3x3 is 729
In 7th grade:
red-hair students =58
another color hair students =609
In 8th grade:
red-hair students =60
Let's assume
another color hair students =x
now, we are given
The numbers of red-haired students in 8th grade are proportional to the numbers in 7th
so,

now, we can solve for x
we get

we get

so, students have another color hair in 8th grade is 630.........Answer
