Răspuns:

Explicație pas cu pas:

a) √(16·9) = √(2⁴·3²) = √(2²·3)² = 2²·3 = 12

b) √(81·625) = √(3⁴·5⁴) = √(3²·5²)² = 3²·5² = 9·25 = 225

c) √(5⁴·17¹⁰) = √(5²·17⁵)² = 5²·17⁵

d) √(2020²·2²⁰²⁰) = √(2000·2¹⁰¹⁰)² = 2000·2¹⁰¹⁰

e) √(22²·3⁴·2⁶) = √(22·3²·2³)² = 22·3²·2³ = 22·72 = 1584

f) √(5⁶·7⁴·10⁸) = √(5³·7²·10⁴)² = 5³·7²·10⁴ = 25·49·10000 =

= 1225·10000 = 12250000
