1).    a). 6 · 12⁻¹ = 6 : 12 = 1/2 = 0,5

      б). -4 · 8⁻² = -4 : 16 = -1/4 = -0,25  

      в). 6⁻¹ - 3⁻² = 1/6 - 1/9 = 1/18

      г). 1,3⁰ + 1,3⁻¹ = 1 + 10/13 = 23/13 = 1 10/13

      д). 12 - (1/6)⁻¹ = 12 - 6 = 6

      e). 2 1/3 · (2/3)⁻² - 0,5 = 7/3 · 9/4 - 0,5 = 21/4 - 2/4 = 19/4 = 4,75

2).  a). 345 = 3,45 · 10²

     б). 4300000 = 4,3 · 10⁶

     в). 0,0000000104 = 1,04 · 10⁻⁸

     г). 0,147 = 1,47 · 10⁻¹

     д). 112200 = 1,122 · 10⁵

     е). 895,2 = 8,952 · 10²
