Answer 2

Answer:

375/8

Step-by-step explanation:

1.Prime Factorise 1080:-

    5║1080

    3║216

    3║72

    3║24

    2║8

    2║4

    2║2

     1║1

   

1080= 2^{3} x 3^{3} x 5^{1}

∴ a=3,b=3,c=1

2.Finding solution:-

  2^{-a} x 3^{c} x 5^{b}

= 2^{-3} x 3^{1} x 5^{3}

= (1/8) x 3 x 125 = 375/8
