    Answer:15

    Step-by-step explanation:

    (a^(2)+a^(-1))^(6)

    =

    (a^(2)+a^(-1))(a^(2)+a^(-1))(a^(2)+a^(-1))(a^(2)+a^(-1))(a^(2)+a^(-1))(a^(2)+a^(-1))

    Applying pascal’s triangle ad expanding

    15+((1)/(a^(6)))+((6)/(a^(3)))+20a^(3)+15a^(6)+6a^(9)+a^(12)

    15x^0 =15 ,since 15 is the number in front of the variable x^0
