Question 1: If shes making 4 hats alone and then Quadruples it shes making 16 hats per week if she quadruples it again she will be knitting 64 hats per week.

4x4=16

16x4=64hats

Question 2: There is an error because 5x5x5 = 5³

Question 3: 2⁴ - 8 x 2 / 4 = 12

2⁴ = 16 - 8 x 2 / 4

8x2 = 16

16/4 = 4

16-4 = 12
