Question

Alguém me ajuda urgente!!! Calcule e simplifique a)√2.√5 b)√3.√15 c)√2.√98 d)√20.√9/20 e)√200.√2 f)√50.√3.6 g)√0,4.√10 h)√8.√1/2

Answer 1

Vamos lá,

a) √2 . √5 = √10

b) √3 . √15 = √45 = 3√5

c) √2 . √98 = √196 = 14

d) √20 . √9/20 = √180 /√20 = √9 = 3

e) √200 . √2 = √400 = 20

f) √50 . √3 . 6 = √50 . √18 = √900 = 30

g) √0,4 . √10 = √4 = 2

h) √8 . √1/2 = √8 / √2 = √4 = 2

Espero ter ajudado ^^

Answer 2

Boa tarde Paola

a) √2*√5 = √10

b) √3*√15 = √45 = √(9*5) = 3√5 

c) √2*√98 = √(2*2*49) = √(2*2*7"7) = 2*7 = 14

d) √20*√(9/20) = √20*9/20) = √9 = 3

e) √200*√2 = √400 = 20 

f) √50*√3*6 = √(25*2*2*9) = 5*2*3 = 30 

g) √0.4*√10 = √4 = 2

h) √8*√/1/2) = √4 = 2
