Answer 2

$a) \: \: 76 : 2 = 38 \\ 38 : 2 = 19 \\ 19 : 19 = 1 \\ \iff \: 76 = 2 {}^{2} \times 19 \\ \\ \\ \\ b) \: 40 : (2 \times 5) = 4 \\ 4 : 2 = 2 \\ 2 : 2 = 1 \\ \iff \: 40 = 2 {}^{3} \times 5 \\ \\ \\ c) \: 44 : 2 = 22 \\ 22 : 2 = 11 \\ 11 : 11 = 1 \\ \iff \: 44 = 2 {}^{2} \times 11 \\ \\ \\ d) \: 250 : (2 \times 5) = 25 \\ 25 : 5 = 5 \\ 5 : 5= 1 \\\iff \: 250 = 5 {}^{3} \times 2$
