Giải thích các bước giải :
`(49^(25).125^(10).2^8-5^(30).7^(49).4^5)/(5^(29).16^(2).7^(48))`
`=((7^2)^(25).(5^3)^(10).2^8-5^(30).7^(49).(2^2)^5)/(5^(29).(2^4)^(2).7^(48))`
`=(7^(50).5^(30).2^8-5^(30).7^(49).2^(10))/(5^(29).2^(8).7^(48))`
`=((7^(49).5^(30).2^8)(7-2^2))/(5^(29).2^(8).7^(48))`
`=7.5.3`
`=105`
Vậy : `(49^(25).125^(10).2^8-5^(30).7^(49).4^5)/(5^(29).16^(2).7^(48))=105`
