Solution - Simplification or other simple results

(2^{32} * 3^{16}) / 5 = 3.69769 * 10^{16}

(2^32*3^16)/5=3.69769*10^16

Step 1 :

 1.1     20736 = 2⁸•3⁴

(20736)⁴ = (2⁸•3⁴)⁴ = 2³² • 3¹⁶

            (2³²•3¹⁶) 
 Simplify   —————————
                5

  (2³²•3¹⁶)                                   
  ————————— = 3.69769 • 10¹⁶ 
      5
