Evaluate the following : (5/7)^3

Evaluate the following: (3/7)^(-5)xx(7/6)^(-4)

Evaluate the following: |[7,5],[-2,3]|

Evaluate each of the following: (-5)/(14)(-2)/(7) (ii) (13)/(15)-(12)/(25) (iii) (-6)/(13)-(-7)/(13)

Evaluate each of the following: (2)/(3)-(3)/(5) (ii) (4)/(7)-(2)/(-3)( iii) (4)/(7)-(-5)/(-7)
