1) 0.5⁸ × 2⁸ = (0.5×2)⁸ = 1⁸ = 1

2) 2⁵ × 5⁵ = 10⁵ = 100000

3) (1/3)⁶ × 6⁶ = (1/3⁶) × 6⁶ = 6⁶/3⁶ = 2⁶×3⁶/3⁶ = 2⁶ = 64

4) 0.125⁹ × 8⁹ = (1/8)⁹ × 8⁹ = 8⁹/8⁹ = 1

5) (1 7/9)¹¹ × (9/16)¹² = 16¹¹/9¹¹ × 9¹²/16¹² = 16¹¹×9¹²/9¹¹×16¹² = 9/16 = 0.5625

6) 0.25²⁰ × 4¹⁸ = (1/4)²⁰ × 4¹⁸ = 4¹⁸/4²⁰ = 1/4² = 1/16 = 0.0625

Відповідь:

1) 0,5⁸ · 2⁸ = (0,5 · 2)⁸ = 1⁸ = 1

2) 2⁵ · 5⁵ = (2 · 5)⁵ = 10⁵ = 100.000

3) ()⁶ · 6⁶ = ( · 6)⁶ = 2⁶ = 128

4) 0,125⁹ · 8⁹ = (0,125 · 8)⁹ = 1⁹ = 1

5) (1)¹¹ · ()¹² = ( ·)¹¹ · = 1¹¹ · = 1 · =

6) 0,25²⁰ · 4¹⁸ = (0,25 · 4)¹⁸ · 0,25² = 1¹⁸ · 0,0625 = 1 · 0,0625 = 0,0625
