1) \(A=\left\{136-32.\left[\left(25:25+17.2016^0\right):3-3\right]\right\}:102.52\)
\(\Rightarrow A=\left\{136-32.\left[\left(1+17\right):3-3\right]\right\}:102.52\)
\(\Rightarrow A=\left[136-32.\left(18:3-3\right)\right]:102.52\)
\(\Rightarrow A=\left[136-32.\left(6-3\right)\right]:102.52\)
\(\Rightarrow A=\left(136-32.3\right):102.52\)
\(\Rightarrow A=\left(136-96\right):102.52\)
\(\Rightarrow A=40:102.52\)
\(\Rightarrow A=\dfrac{20}{51}.52\)
\(\Rightarrow A=\dfrac{1040}{51}\)
[545 - (45 + 4 x 25)] : 50 - 200 : 250 + 215 : 213
= [545 - (45 + 100)] : 50 - 200 : 250 + 22
= (545 - 4500) : 50 - 200 : 254
= (-3955) : 50 + 200 : 254
= [(-3955) + 200] : (50 + 254)
= (-3755) : 304
= bạn tự tính nha
[504 - (25 x 8 + 70)] : 9 - 15 + 190
= [504 - (200 + 70)] : 9 - 15 + 0
= (504 - 270) : 9 - 15
= 234 : 9 - 15
= 26 - 15
= 9
5 x {26 - [3 x 5 + 2 x 5 + 15] : 15}
= 5 x {26 - [(3 + 2) x 5) + 15] : 15}
= 5 x {26 - [5 x 5 + 15] : 15}
= 5 x [26 - (25 + 15) : 15]
= 5 x (26 + 25 - 15 : 15)
= 5 x (51 - 1)
= 5 x 50 = 250
d) [1104 - (25 x 8 + 40)] : 9 + 316 : 312
= [1104 - (200 + 40)] : 9 + 34
= (1104 - 240) : 9 + 81
= 864 : 9 + 81
= 96 + 81
= 177
Học tốt!!!
\(a,=43\left(203-103\right)-3\cdot100=43\cdot100-3\cdot100\\ =100\left(43-3\right)=100\cdot40=4000\\ b,=40-40\cdot1+9^{18}-1\\ =9^{18}-1\\ c,=25\left[32:\left(155-3\cdot7^2\right)\right]=25\left[32:\left(155-147\right)\right]\\ =25\left(32:8\right)=25\cdot4=100\)
a: \(203\cdot43-103\cdot43-300=43\cdot100-300=4000\)
b: \(40-40\cdot2018^0+9^{18}-9^0\)
\(=40-40+9^{18}-1\)
\(=9^{18}-1\)
