lộn xộn quá cậu viết lại qua kí tự " gõ công thức toán đi"
Mk gõ lại cho
\(\left(\frac{173535}{88375}-\frac{161001}{1365}\right)x3\frac{6}{23}:\left(5-1\frac{187}{253}\right)\)

Lời giải chi tiết:
40 + 8 = 48 | 30 + 5 = 35 | 23 + 6 = 29 | 65 + 3 = 68 |
60 + 1 = 61 | 90 + 2 = 92 | 23 + 60 = 83 | 3 + 65 = 68 |

a/=23.(64+37-1)
=23.100
=2300
b/=(33,76+6,24)+19,52
=40+19,52
=59,52
c/=38/11+16/13+6/11
=(38/11+6/11) +16/13
=44/11+16/13
=4+1/3/13
=5/3/13
d/=3/4.5/3-1/5
=5/4-1/5
=25/20-4/20
=21/20
=1/1/20
tick đúg mk nha

a: \(=\dfrac{17}{7}+\dfrac{2}{9}-\dfrac{10}{7}-\dfrac{5}{3}\cdot9=1+\dfrac{2}{9}-15=-14+\dfrac{2}{9}=-\dfrac{126}{9}+\dfrac{2}{9}=-\dfrac{124}{9}\)
b: \(=\dfrac{-11}{23}\left(\dfrac{6}{7}+\dfrac{8}{7}\right)-\dfrac{1}{23}=\dfrac{-22}{23}-\dfrac{1}{23}=-1\)
c: \(=\left(\dfrac{377}{-231}-\dfrac{123}{89}+\dfrac{34}{791}\right)\cdot\dfrac{4-3-1}{24}=0\)
d: \(=\dfrac{12}{7}\left(19+\dfrac{5}{8}-15-\dfrac{1}{4}\right)=\dfrac{12}{7}\cdot\dfrac{35}{8}=\dfrac{15}{2}\)
![](https://rs.olm.vn/images/avt/0.png?1311)
\(B=\left(17+\dfrac{1}{25}-16-\dfrac{11}{15}\right)\cdot\dfrac{75}{23}+\dfrac{75}{23}\cdot\dfrac{23}{75}\)
\(=\dfrac{23}{75}\cdot\dfrac{75}{23}+1=1+1=2\)
= 23x(1+6+3)
= 23x10
=230
23*1+23*6+23*3=23+138+69=245
