Sửa đề:
13².181 - 5².181 + 144.19
= 169.181 - 25.181 + 144.19
= 181.(169 - 25) + 144.19
= 181.144 + 144.19
= 144.(181 + 19)
= 144.200
= 28800
\(13^2\cdot181-5^2:181+144\cdot19\)
\(=169\cdot181-25:181+144\cdot19\)
\(=30589-\dfrac{25}{181}+2736\)
\(=30588,86188+2736\)
\(=33324,86188\)

$-(181 + 72 - 5) + (95 - 181 + 72)$
$=-181 - 72 + 5 + 95 - 181 + 72$
$= (-181 -181) + (72 - 72) + (5 + 95)$
$= -362 + 100 = -262$.

\(\left(2017-\dfrac{5}{181}+\dfrac{1}{50}\right)-\left(4+\dfrac{3}{181}-\dfrac{2}{50}\right)+\left(1-\dfrac{8}{181}+\dfrac{3}{50}\right)\)
\(=2017-\dfrac{5}{181}+\dfrac{1}{50}-4-\dfrac{3}{181}+\dfrac{2}{50}+1-\dfrac{8}{181}+\dfrac{3}{50}\)
\(=2014+\dfrac{143}{4525}\)
\(=\dfrac{9113493}{4525}\)

\(-359+181+(-123)+350+(-172)\\=(-359+350)+[181+(-172)] +(-123)\\=-9+9-123\\=-123\)
359+181+(−123)+350+(−172)
=(−359+350)+[181+(−172)]+(−123)
=−9+9−123
=−123

378 - ( 181 - x ) = 215
181 - x = 378 - 215
181 - x = 163
x = 181 - 163
x = 18
Làm ơn tick cho mink với nhé!!***
378-(181-x)=215
=> 181-x=378-215
=> 181-x=163
=> x=181-163
=> x=18
Vậy x=18

3x + 181 = 465
3x = 465 - 181
x = 284 : 3
x = \(\frac{284}{3}\)
