\(C=9\cdot\left(\frac{\frac{26299}{2023}-\frac{3757}{2023}-\frac{91}{2023}}{\frac{8092}{2023}-\frac{1156}{2023}-\frac{28}{2023}}\right):\left(\frac{\frac{840255}{21545}+\frac{168051}{21545}+\frac{6045}{21545}+\frac{27105}{21545}}{\frac{344720}{21545}+\frac{68944}{21545}+\frac{2480}{21545}+\frac{11120}{21545}}\right)\cdot\frac{158158}{164164}\)
\(C=9\cdot\left(\frac{\frac{22451}{2023}}{\frac{6908}{2023}}\div\frac{\frac{1041456}{21545}}{\frac{427264}{21545}}\right)\cdot\frac{158158}{164164}\)
\(C=9\cdot\left(\frac{13}{4}\div\frac{39}{16}\right)\cdot\frac{158158}{164164}\)
\(C=9\cdot\frac{4}{3}\cdot\frac{2\cdot79\cdot2\cdot79}{2\cdot82\cdot2\cdot82}=9\cdot\frac{4}{3}\cdot\frac{79}{82}\)
\(C=\frac{474}{41}\)
\(\frac{12.\left(1-\frac{1}{7}-\frac{1}{289}-\frac{1}{85}\right)}{4.\left(1-\frac{1}{7}-\frac{1}{289}-\frac{1}{85}\right)}:\frac{3.\left(1+\frac{1}{13}+\frac{1}{169}+\frac{1}{91}\right)}{7.\left(1+\frac{1}{13}+\frac{1}{169}+\frac{1}{91}\right)}\)
\(=3:\frac{3}{7}=7\)
\(\left(57-289\right)-\left(76-289\right)+\left(176+43\right)\)
\(=\) \(\left(-232\right)\) \(-\) \(\left(-213\right)\) \(+\) \(219\)
\(=\) \(\left(-19\right)+219\)
\(=200\)
(57 - 289 ) - ( 76 - 289 ) + ( 176 + 43 )
= 57 - 289 - 76 +289 +176 +43
= (57 + 43 ) + ( -289 +289 ) + ( - 76 + 176 )
= 100 +100
=200
Sao ban chui ban ay?
3-(17-x)=289-(36+289)
3-(17-x)=-36
17-x=-36+3
17-x=39
x=17-39
x=-22
Nho cho mk nhe!!!!!!
3-(17-x)=289-(36+289)
3-(17-x)=-36
17-x=39
x=17-39
x=-22
Vay x=-22
Nho cho mk 1 h nha!!!
-(-3793+289)+(-3793+289)+(-37)
=3793-289-3793+289-37
= (3793-3793) +(289-289)-37
=-37
