các pác trình bày tình bước ra giúp cháu cx đc ạ

a,\(0,5-\frac{5}{41}+\frac{1}{2}-\frac{36}{41}\)

=\(\frac{1}{2}-\frac{5}{41}+\frac{1}{2}-\frac{36}{41}\)

=\(\left(\frac{1}{2}+\frac{1}{2}\right)-\left(\frac{5}{41}+\frac{36}{41}\right)\)

= \(1-1=0\)

b,\(\left(\frac{-1}{3}\right)^2.\frac{4}{11}+\frac{7}{11}.\left(\frac{1}{3}\right)^2\)

=\(\frac{1}{9}.\frac{4}{11}+\frac{7}{11}.\frac{1}{9}\)

=\(\frac{1}{9}\left(\frac{4}{11}+\frac{7}{11}\right)\)

=\(\frac{1}{9}.1=\frac{1}{9}\)

c,\(\left(\frac{-2}{3}+\frac{3}{7}\right):\frac{4}{5}+\left(\frac{-1}{3}+\frac{4}{7}\right):\frac{4}{5}\)

=\(\left(\frac{-2}{3}+\frac{3}{7}-\frac{1}{3}+\frac{4}{7}\right):\frac{4}{5}\)

=\(\left(-1+1\right).\frac{5}{4}=0.\frac{5}{4}\)=0

cảm ơn

a) ( 22 + 15 ).( -4 ) + 11. ( 36 - 21 )

= 35.(-4) + 11.15

= (-140) + 165
