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

\(13^2\cdot181-5^2:181+144\cdot19\)

\(=169\cdot181-25:181+144\cdot19\)

\(=30589-\dfrac{25}{181}+2736\)

\(=30588,86188+2736\)

\(=33324,86188\)

   $-(181 + 72 - 5) + (95 - 181 + 72)$

$=-181 - 72 + 5 + 95 - 181 + 72$

$= (-181 -181) + (72 - 72) + (5 + 95)$

$= -362 + 100 = -262$.

111+111+111+111+111+111

= 111.6

= 666

= 111 x 6

= 666

chúc bn hk tốt.

111+111+111+111+111+111

=111*6

=666

= 1 + 11 + 111 x 5

= 12 + 555 

= 567

1 + 11 + 111x5 = 1+11+555=567

=1+11  111x5

=  12      555

=567

kết quả = 222 222 222 

mik ko phải ARMY nhưng k mik nhé

\(111+111+111+111+222-666\)

\(=111.4+222-666\)

\(=444+222-666\)

\(=666-666\)

\(=0\)

_Chúc bạn học tốt_

111 + 111 + 111 + 111 + 222 - 666

= 444 + 222 - 666

= 666 - 666

= 0

Chúc bạn học tốt !

Bằng 0 nha bạn

444

111+111+111+111=111x4=444
Dễ mà :)

bằng 111 nhân 3

=333

\(\left(2017-\dfrac{5}{181}+\dfrac{1}{50}\right)-\left(4+\dfrac{3}{181}-\dfrac{2}{50}\right)+\left(1-\dfrac{8}{181}+\dfrac{3}{50}\right)\)

\(=2017-\dfrac{5}{181}+\dfrac{1}{50}-4-\dfrac{3}{181}+\dfrac{2}{50}+1-\dfrac{8}{181}+\dfrac{3}{50}\)

\(=2014+\dfrac{143}{4525}\)

\(=\dfrac{9113493}{4525}\)
