Bonjour,
a) 3 x 3 x 3 x 5 x 5 x 5 x 5 = 3^3 x 5^4
b) 4 x 2 x 3 x 4 x 3 x 2 = 2 x 2 x 2 x 3 x 2 x 2 x 3 x 2 = 2^6 x 3^2
c) 2 x 2 x 5 x 5 x 2 x 5 x 2 x 5 x 2 x 5 = 2^5 x 5^5
d) 7 x 7 x 3 x 3 x 3 x 7 x 3 = 3^4 x 7^3
e) 8 x 2 x 8 x 8 x 4 x 2 = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 2^13
f) 2 x 13 x 3 x 13 x 9 x 4 = 2 x 13 x 3 x 13 x 3 x 3 x 2 x 2 = 2^3 x 3^3 x 13^2
