= 198 : [130 - 64 ] +1
= 198 : 66 + 1
= 3 + 1
= 4
=198:[130-(27-19)2 ]+1
=198:[130-64]+1
=198:66+1

Bài 1: Thực hiện phép tính:
a) 25. 69 + 31. 25 – 150; b) 198 : [130 – (27 – 19 )2] + 20210 ;
c) 520 : (515.15 + 515.10).
a) 25. 69 + 31. 25 – 150;
b) 198 : [130 – (27 – 19 )2] + 20210 ;
c) 520 : (515.15 + 515.10).
d) 27– (15 – 31) – (– 2 + 21+ 5)
e) 47 – (23 + 17) – (– 17 + 47)
f) 34 – [(–12) + 34] – (49 + 12) g) 72 – (15 – 14 + 72) + 52
198 : [130 – (27 – 19 )^2] + 2021^0
198:(130-(27-19)^2)+2021^0
a) - 23+150(-9)+1913
b) 2 MŨ2 .5 + ( 49 – 17 MŨ 2 )
c) 25. 69 + 31. 25 – 150; d) 198 : [130 – (27 – 19 ) MŨ 2] + 2021 MŨ 0
Tính
A. ( -25 -35) : 12 - (-198)
B. 19 - (-67) - 67 : 81 -3200
C. (-3)12 : 813 - (-498) + 22
D. 49 (27 - 95) - 27 (49 - 95)
E. 12 . 4 - 24 (2-79) + 79 . 76
Thực hiên phép tính sau
a) 49 - ( -54) - 23
b) (-103) + 49 - (-54) -|-23|
c) 19 . 87 + 13. 19 - 130
d) 2448 : [119 -( 23 - 6) ]
e) 27 . 75 + 25 . 27 - 150
g)24 .5 [131 - (13 - 4)2 ]
Ai nhanh mình tick nha
24 .5 - [131- (13 -4)2] + 20210
2011 – [39 – (23.3 – 21)2] : (-3)+ 20210
