Đáp án:
`=64/15625`
Giải thích:
`[(5^4-5^3)^3]/[125^5`
`=[(625-125)^3]/[(5^3)^5]`
`=[(500)^3]/5^(3.5)`
`=[(5.100)^3]/5^(3.5)`
`=[5^3. 100^3]/5^15`
`=(1.100^3)/(5^12)`
`=100^3/5^12`
`=(5.5 .4)^3/5^12`
`=(5^3 . 5^3 . 4^3)/(5^12)`
`=[5^(3+3 ). 4^3]/5^12`
`=(5^6 . 4^3)/5^12`
`=(1.4^3)/(5^6)`
`=4^3/5^6`
`=64/15625`
