(root 4)^-7 (root2)^-5
= (root 2)^(-2/7) (root2)^-5
now,
= (-2/7.) + (-1/5)
= [(-2)*(5)+ (-5)* (7) ]/ 35
= [-10 + (-35) ] /35
= [-10. -35. ] /35
= -45 / 35
= -9 / 7
= (root 2)^(-2/7) (root2)^-5
now,
= (-2/7.) + (-1/5)
= [(-2)*(5)+ (-5)* (7) ]/ 35
= [-10 + (-35) ] /35
= [-10. -35. ] /35
= -45 / 35
= -9 / 7
