Mọi người giúp mình với ạ , mình cảm ơn

 

Answer 1

\(a,=\dfrac{9}{4}+\dfrac{5}{6}-\dfrac{3}{2}\cdot\dfrac{1}{6}=\dfrac{37}{12}-\dfrac{1}{4}=\dfrac{17}{6}\\ b,=-\dfrac{5}{3}\left(16\dfrac{2}{7}-28\dfrac{2}{7}\right)=-\dfrac{5}{3}\left(-12\right)=20\\ c,M=\dfrac{2^{60}+2^{40}}{2^{50}+2^{30}}=\dfrac{2^{40}\left(2^{20}+1\right)}{2^{30}\left(2^{20}+1\right)}=2^{10}=1024\\ d,=\left(\dfrac{3}{2}-\dfrac{1}{2}\right)\cdot\dfrac{1}{9}+\dfrac{1}{6}=\dfrac{1}{9}+\dfrac{1}{6}=\dfrac{5}{18}\)
