Quanto e raiz quadrada de:
A)3/4
B)9/7
C)36/81
D)2/7
E)3/5
Aplicando a regra de divisao
(35)1/2 = (5,91607978309962 × 5,91607978309962)1/2
(35)1/2 = [(5,91607978309962)2]1/2
(35)1/2 = (5,91607978309962)2/2
(35)1/2 = (5,91607978309962)1
Logo,
√35 = 5,91607978309962
Soluções para a tarefa
Resposta:
Explicação passo a passo:
a) A raíz quadrada de 3,4 é definida como o número real positivo tal que, multiplicado por sí mismo, resulta em 3,4.
A raíz quadrada de 3,4 pode ser escrita como (3,4)1/2. Assim,
(3,4)1/2 = (1,84390889145858 × 1,84390889145858)1/2
(3,4)1/2 = [(1,84390889145858)2]1/2
(3,4)1/2 = (1,84390889145858)2/2
(3,4)1/2 = (1,84390889145858)1
√3,4 = 1,84390889145858
b) (9,7)1/2. Assim,
(9,7)1/2 = (3,11448230047949 × 3,11448230047949)1/2
(9,7)1/2 = [(3,11448230047949)2]1/2
(9,7)1/2 = (3,11448230047949)2/2
(9,7)1/2 = (3,11448230047949)1
Logo,
√9,7 = 3,11448230047949
c) (3681)1/2. Assim,
(3681)1/2 = (60,67124524847005 × 60,67124524847005)1/2
(3681)1/2 = [(60,67124524847005)2]1/2
(3681)1/2 = (60,67124524847005)2/2
(3681)1/2 = (60,67124524847005)1
Logo,
√3681 = 60,67124524847005
(27)1/2 = (5,19615242270663 × 5,19615242270663)1/2
(27)1/2 = [(5,19615242270663)2]1/2
(27)1/2 = (5,19615242270663)2/2
(27)1/2 = (5,19615242270663)1
Logo,
√27 = 5,19615242270663
