Giải thích các bước giải:
Bài 1 :
a ) 160 – 60 . 2 + 164
= 160 – 120 + 164
= 40 + 164
= 204
b ) $3^{3}$ . $2012^{2013}$ . 0 + [ $4^{3}$ – $(89-87)^{2}$ ] . $1^{2012}$
= $3^{3}$ . 0 + ( $4^{3}$ – $2^{2}$ ) . 1
= 0 + 60 . 1
= 0 + 60
= 60
Bài 2 :
a ) 77 . 35 + 35 . 23
= 35 . ( 77 + 23 )
= 35 . 100
= 3500
b ) $9^{2}$ . 3 : $3^{5}$ + $11^{34}$ : $11^{32}$
= $3^{4}$ . 3 : $3^{5}$ + $11^{2}$
= $3^{5}$ : $3^{5}$ + 121
= 1 + 121
= 122
Bài 1:
a) `160-60.2+164`
`= 160-120+164`
`= 40+164`
`= 204`
b) `3³.2012^2013 .0+[4³-(89-87)²].1^2012`
`= 3³.0+[64-4].1`
`= 0+60.1`
`= 60`
Bài 2:
a) `77.35+35.23`
`= 35.(77+23)`
`= 35.100`
`= 3500`
b) `9².3÷3^5 +11^34 ÷11^32`
`= 3^5 ÷3^5 +11²`
`= 1+121=122`
