A) 2⁷ * 5⁷ = (2 * 5 ) ⁷ = 10⁷ = 10000000
b) (½)⁵ * 4⁵ = (½ * 4 ) ⁵ = 2⁵ = 32
c) 16¹⁰ : 8¹⁰ = ( 16 : 8 ) ¹⁰ = 2 ¹⁰ = 1024
d) (³/₅)⁴ : (¹/₅)⁴ = (⅗ : ⅕) ⁴ = (⅗ * ⁵₁ )⁴ = 3 ⁴ = 81
e) 0,2³ * 10³ = ( 0,2 * 10 ) ³ = 2 ³ = 8
f) (-0,1)⁴ * 5⁴ = (-0,1 * 5 )⁴ = (-0,5)⁴ = 0.0625
g) (-¹/³) : (-¹/₉)³ = (-⅓ : -¹/₉) ³ = (-⅓ * 9) ³ = -3³ = -27
h) (-2)⁸ : (-0,2)⁸ = (-2 : - 0,2) ⁸ = 10 ⁸ = 100000000

A) 2⁷ * 5⁷ = (2 * 5)⁷ = 10⁷ = 10`000`000
b) (½)⁵ * 4⁵ = (½ * 4)⁵ = 2⁵ = 32
c) 16¹⁰ : 8¹⁰ = (16 : 8)¹⁰ = 2¹⁰ = 1024
d) (³/₅)⁴ : (¹/₅)⁴ = (³/₅ * ⁵/₁)⁴ = 3⁴ = 81
e) 0,2³ * 10³ = (0,2 * 10)³ = 2³ = 8
f) (-0,1)⁴ * 5⁴ = (-0,1 * 5)⁴ = (-½)⁴ = ¹/₁₆
g1) (-¹/³) : (-¹/₉)³ = a tu chyba jakiś błąd jest (nie to ze nie policzę, ale się znacznie różni od reszty) =
(-⅓):(-(⅓)²)³ = (-⅓):-(⅓)⁶ = 1 : ⅓⁵ = ⅓⁻⁵ = 243
No chyba ze to mialo byc z (-¹/₃)³
g2) (-¹/₃)³ : (-¹/₉)³ = (-⅓ : -¹/₉) ³ = (-⅓ * 9) ³ = -3³ = -27
h) (-2)⁸ : (-0,2)⁸ = (-2 * -¹⁰/₂)⁸ = 10⁸ = 100`000`000
