​

Answer 1

Răspuns:

c) (5/10)³ × 2³

= (5/10 × 2)³

= (1/2 × 2)³

= 1³ = 1 .

d) (0,25)⁴ × 4⁴

= (0,25 × 4)⁴

= 1⁴

= 1 .

e) (12/100)¹⁴⁹ × (8 1/3)¹⁴⁹

= (12/100 × 8 1/3)¹⁴⁹

= (12/100 × 25/3)¹⁴⁹

= (4/100 × 25)¹⁴⁹

= (4/4)¹⁴⁹

= 1¹⁴⁹

= 1 .

f) (8 1/3)⁴ × (24/10)⁴

= (8 1/3 × 24/10)⁴

= (25/3 × 24/10)⁴

= (25 × 8/10)⁴

= (5 × 8/2)⁴

= (5 × 2)⁴

= 20⁴

= 160 000
