Răspuns: a) 2¹² b) 3⁹⁰ c) 5⁴ d) 2²⁴
Explicație pas cu pas:
a) (2¹⁰)³:4⁹= 2³⁰:(2²)⁹
= 2³⁰:2¹⁸
= 2¹²
b) (3²⁰)⁴×(9¹⁰)²:27¹⁰ = 3⁸⁰×9²⁰:(3³)¹⁰
= 3⁸⁰×(3²)²⁰:3³⁰
= 3⁸⁰×3⁴⁰:3³⁰
= 3¹²⁰:3³⁰
= 3⁹⁰
c) 25¹⁰×5¹⁴:125¹⁰ = (5²)¹⁰×5¹⁴:(5³)¹⁰
= 5²⁰×5¹⁴:5³⁰
= 5³⁴:5³⁰
= 5⁴
d) 2⁵×4²×32³ = 2⁵×(2²)²×(2⁵)³
= 2⁵×2⁴×2¹⁵
= 2²⁴
