Giải thích các bước giải:
2^12 . 3^5 – 4^6 . 81 / ( 2^2 . 3 )^6 + 8^4 . 3^5
=2^12.3^5-(2^2)^6.3^4/2^12.3^6+(2^3)^4.3^5
=2^12.3^5-2^12.3^4/2^12.3^6+2^12.3^5
=2^12.(3^5-3^4)/2^12.(3^6+3^5)
=3^5-3^4/3^6+3^5
=3^4.(3-1)/3^5.(3+1)
=3^4.2/3^5.4
=1.1/3.2

`=1/6`
Giải thích các bước giải:
`(2^12 . 3^5 – 4^6 . 81) /( ( 2^2 . 3 )^6 + 8^4 . 3^5)`
`=(2^12 . 3^5 – (2^2)^6 . 3^4) /( ( 2^2)^6 . 3 ^6 + (2^3)^4 . 3^5)`
`=(2^12 . 3^5 – 2^12 . 3^4) /( 2^12 . 3 ^6 + 2^12 . 3^5)`
`=(2^12 .( 3^5 – 3^4)) /( 2^12 .( 3 ^6 + 3^5))`
`=(3^5 – 3^4 )/(3^6 + 3^5)`
`=(3^4 . ( 3-1))/(3^5 . ( 3+1))`
`=(3^4 . 2)/(3^5 . 4)`
`=(1.1)/(3.2)`
`=1/6`
