(1/3)^50 × (1/5)^49 : (1/15)^50 =

= (1/3)^50 ×(1/5)^49:[ (1/3)^50 ×(1/5)^50] =

=( 1/5)^49 : (1/5)^50 =

= (1/5)^49-50 =

= (1/5)^-1 =

(1/3^50) * (1/5^49) : (1/15^50) = (1/3^50) * (1/5^49) * 15^50 = (1/3^50) * (1/5^49) * (3*5)^50 = (1/3^50) * (1/5^49) * 3^50*5^50 = 3^(50-50) * 5^(50-49) = 1 * 5 = 5
