\(M=\left(\dfrac{4}{9}-\dfrac{7}{11}\right)-\dfrac{4}{9}-\dfrac{3}{11}\)

\(=\dfrac{4}{9}-\dfrac{7}{11}-\dfrac{4}{9}-\dfrac{3}{11}\)

\(=\left(\dfrac{4}{9}-\dfrac{4}{9}\right)-\left(\dfrac{7}{11}+\dfrac{3}{11}\right)\)

\(=0-\dfrac{10}{11}=-\dfrac{10}{11}\)

= 13/30

\(96-4:\left[\left(11-9\right)^5:\left(7-5\right)^3\right]\)

\(96-4:\left[2^5:2^3\right]=96-4:\left[2^2\right]=96-4:4=96-1=95\)

96 - 4: [ (11 - 9)⁵ : ( 7 - 5)³ ] 

96 - 4 : [ 2⁵ : 2³ ]

96 - 4: 2²

= 96 - 4: 4

= 96 - 1

= 95
