Question

Resposta com cálculo! Alguém?

Answer 1

14 x 14= 196
25 x 25= 625
-3 x -3 x -3= -27

Answer 2

a)
$\sqrt{196} = \sqrt{2^2.7^2} =2.7=14$

b)
$\sqrt{625} = \sqrt{5^4} =5^2=25$

c)
$\sqrt[3]{-27} = \sqrt[3]{-3^3} =-3$

d)
$\sqrt[5]{1024} = \sqrt[5]{2^{10}} =2^2=4$

e)
$- \sqrt{625} =- \sqrt{5^4} =-5^2=-25$

f)
$\sqrt[4]{-64} =$ não existe raiz

g)
$\sqrt[4]{625} = \sqrt[4]{5^4} =5$

h)
$\sqrt[3]{1000} = \sqrt[3]{2^3.5^3} =2.5=10$

i)
$\sqrt[5]{ \frac{1}{32} } = \sqrt[5]{( \frac{1}{2})^5 } = \frac{1}{2}$
