a) 5 ^ 8 : 5 ^5 – 4^3 . 1^10
b) 10 ^ 3 . 10 ^2 + 4 ^5 : ( 10 – 6^3)
Đáp án:
`a)` `5 ^ 8 : 5 ^5 – 4^3 . 1^10`
`=5^3 – 64 . 1`
`=125 – 64`
`= 61`
`b)` `10 ^ 3 . 10 ^2 + 4 ^5 : ( 10 – 6^3)`
`= 10^5 + 1024 : (10 – 216)`
`=100000 – 512/103`
Giải thích các bước giải:
`a) 5 ^ 8 : 5 ^5 – 4^3 . 1^10`
`=125-64*1`
`=61`
`b) 10 ^ 3 . 10 ^2 + 4 ^5 : ( 10 – 6^3)`
`=100000+1024:(-206)`
`=100000-512/103`
