Thực hiện phép tính a) 3^5:3^2- 2.2 - (10^0 + 8) : 3 + 5 b) 152 – {120 : [8^2 - (21 + 36 : 3^2) + 2017^0]} c) 2^3.2^2 - (5^6 : 5^4 - 2010^0.24)^3 - 14

Lời giải chi tiết:

`a)` `3^5:3^2-2.2-(10^0+8):3+5`

`=3^3-4-(1+8):3+5`

`=27-4-9:3+5`

`=23-3+5`

`=20+5`

`=25`

`b)` `152-{120:[8^2-(21+36:3^2)+2017^0]}`

`=152-{120:[64-(21+36:9)+1]}`

`=152-{120:[64-(21+4)+1]}`

`=152-[120:(64-25+1)]`

`=152-[120:(39+1)]`

`=152-(120:40)`

`=152-3`

`=149`

`c)` `2^(3).2^2-(5^6:5^4-2010^(0).24)^3-14`

`=2^5-(5^2-1.24)^3-14`

`=32-(25-24)^3-14`

`=32-1^3-14`

`=32-1-14`

`=31-14`

`=17`
