Answer 1

[Thuốc Hồi Trinh]

a) 2.3.6.6.6 = 2^1 * 3^1 * 2^1 * 3^1 * 2^1 * 3^1 = 2^3 * 3^3

b) 4.4.5.5.5 = 2^2 * 2^2 * 5^1 * 5^1 * 5^1 = 2^4 * 5^3

c) 2.2.2.8.4 = 2^1 * 2^1 * 2^1 * 2^3 * 2^2 = 2^8

d) 10.10.4.5.5 = 2^1 * 5^1 * 2^1 * 5^1 * 2^2 * 5^2 = 2^4 * 5^4

e) 8.8.4 = 2^3 * 2^3 * 2^2 = 2^8

Answer 2

[Nguyễn Đức Trí]

a) \(2.3.6.6.6=2.3.6^3=2.3.2^3.3^3=2^4.3^4\)

b) \(4.4.5.5.5=4^2.5^3=2^4.5^3\)

c) \(2.2.2.8.4=2^2.2^3.2^2=2^7\)

d) \(10.10.4.5.5=2.5.2.5.2^2.5^2=2^4.5^4\)

e) \(8.8.4=2^3.2^3.2^2=2^8\)
