Answer 2

sorry

Answer 3

84/2=42
42/2=21
21/3=7
7/7=1

2*2*3*7=84

Answer 4

you can do a factor tree

84 factors into 2*42

Answer 5

divide 42 in half to get

42/2 = 21

so 42 = 2*21

Answer 6

21/2 isn't a whole number

but 21/3 = 7 is a whole number

21 = 3*7

Answer 7

now just circle all the prime numbers



and multiply them out

\[\Large 2*2*3*7 = 2^2*3*7 = 84\]

Answer 8

btw this is basically the same steps as @AlexandervonHumboldt2 showed above

just in factor tree form

Answer 9
