Step by step explanation

( 7 / 11 )²m × ( 11 / 7 )⁴ = ( 49/121)-³

= ( 7 / 11 )²m × ( 11 / 7 )⁴ = ( 121 / 49 )³

= ( 7 / 11 )²m × ( 11 / 7 )⁴ = ( 11² / 7² )³ = [ ( 11 / 7 )² ]³ = ( 11 / 7 )⁶

= ( 7 / 11 )²m = ( 11 / 7 )⁶ / ( 11 / 7 )⁴ = [ ( 7 / 11 )²m ] = [ ( 11 / 7 )² ]

= ( 7 / 11 )²m = ( 7 / 11 )-² = 2m = -2

m = -1
