4² x 8³

= ( 2² ) ² x  (  2³ ) ³

= 2⁴ x 2⁹ = 2¹³

4^2*8^3

=(2^2)^2*(2^3)^3

=2^4*2*9

=2^13

4²x8³=4²x(8x8)²=4²x64²=(4.64)²=256²

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

9^8:3^2=9^8:9=9^7 

9^8=43046721

3^2=9

k mk nha!

thanks

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)
