3⁵ . 4⁵  = ( 3.4 )⁵ = 12⁵

8⁵ . 2³ = ( 2⁴ )⁵ . 2³ = 2²⁰ . 2³ = 2^{20 + 3} = 2²³

kb với mk nha các bạn

3⁵.4⁵.8⁵.2³= (3 . 4 . 8)³ . 8

3⁵ ; 4⁵ ; 8⁵ ; 2³

2^(10 : 64 x 16) = 2^[(10 x 16) : 64] = 2^(160 : 64) = 2^25

2^(10 x 8) = 2^80     3^(5 : 27) = 3^(5/27)     5^(2 x 125) = 5^250     6^(6 : 36) = 6^(1/6)

a) \(3^5.3^7=3^{5+7}=3^{12}\)

b) \(a^5.a=a^{5+1}=a^6\)

c) \(5^4:5^3=5^{4-3}=5^1=5\)

d) \(a^3:a^3=a^{3-3}=a^0=1\)

a) \(3^5.3^7=3^{12}\)
