Giải thích các bước giải:
`C=(2^7 .6^5 .4^6 .9^2)/(12^6 +8^4 .3^5)`
`C=(2^7 .(2.3)^5.(2^2)^6.(3^2)^2)/((2^2 .3)^6+(2^3)^4 .3^5)`
`C=(2^7 .2^5 .3^5 .2^12 .3^4)/(2^12 .3^6 +2^12 .3^5)`
`C=(2^24 . 3^9)/(2^12.(3^6 +3^5))`
`C=(2^12 .3^9)/(3^6 +3^5)`
`C=(2^12 .3^9)/(3^5.(3+1))`
`C=(2^12 .3^9)/(3^5 .2^2)`
`C=(2^10 .3^4)/(1.1)`
`C=2^10 .3^4`
`C=82944`
