i)300 / j)27 / k)38

Resposta:

A) (484)1/2. Assim,

(484)1/2 = (22 × 22)1/2

(484)1/2 = [(22)2]1/2

(484)1/2 = (22)2/2

(484)1/2 = (22)1

Logo,

√484 = 22

B) (3,600)1/2. Assim,

(3,600)1/2 = (1,89736659610103 × 1,89736659610103)1/2

(3,600)1/2 = [(1,89736659610103)2]1/2

(3,600)1/2 = (1,89736659610103)2/2

(3,600)1/2 = (1,89736659610103)1

Logo,

√3,600 = 1,89736659610103

C) (1089)1/2. Assim,

(1089)1/2 = (33 × 33)1/2

(1089)1/2 = [(33)2]1/2

(1089)1/2 = (33)2/2

(1089)1/2 = (33)1

Logo,

√1089 = 33

E) (1764)1/2. Assim,

(1764)1/2 = (42 × 42)1/2

(1764)1/2 = [(42)2]1/2

(1764)1/2 = (42)2/2

(1764)1/2 = (42)1

Logo,

√1764 = 42

F) (324)1/2. Assim,

(324)1/2 = (18 × 18)1/2

(324)1/2 = [(18)2]1/2

(324)1/2 = (18)2/2

(324)1/2 = (18)1

Logo,

√324 = 18

G) (1936)1/2. Assim,

(1936)1/2 = (44 × 44)1/2

(1936)1/2 = [(44)2]1/2

(1936)1/2 = (44)2/2

(1936)1/2 = (44)1

Logo,

√1936 = 44

I) (90,000)1/2. Assim,

(90,000)1/2 = (9,48683298050514 × 9,48683298050514)1/2

(90,000)1/2 = [(9,48683298050514)2]1/2

(90,000)1/2 = (9,48683298050514)2/2

(90,000)1/2 = (9,48683298050514)1

Logo,

√90,000 = 9,48683298050514

J) (729)1/2. Assim,

(729)1/2 = (27 × 27)1/2

(729)1/2 = [(27)2]1/2

(729)1/2 = (27)2/2

(729)1/2 = (27)1

Logo,

√729 = 27

K) (1444)1/2. Assim,

(1444)1/2 = (38 × 38)1/2

(1444)1/2 = [(38)2]1/2

(1444)1/2 = (38)2/2

(1444)1/2 = (38)1

Logo,

√1444 = 38
