Answer 1

Răspuns:

a) (5²)¹⁰×5³²×(5³)⁵=5²⁰×5³²×5¹⁵=5⁶⁷

b) (3²)⁴×(3³)⁵×3¹⁴=3⁸×3¹⁵×3¹⁴=3³⁷

c) 2¹⁵×(2²)¹²×(2³)⁶=2¹⁵×2²⁴×2¹⁸=2⁵⁷

Answer 2

Răspuns:

a) 25¹⁰×5³²×125⁵=

=(5²)¹⁰×5³²×(5³)⁵

=5²⁰×5³²×5¹⁵=

=5⁶⁷

b) 9⁴×27⁵×3¹⁴

=(3²)⁴×(3³)⁵×3¹⁴

=3⁸×3¹⁵×3¹⁴

=5³⁷

c) 2¹⁵×4¹²×8⁶

=2¹⁵×(2²)¹²×(2³)⁶

=2¹⁵×2²⁴×2¹⁸

=2⁵⁷
