Question

Calcule:

A) x² =100
B) X² =64
c) X² = 1600
D) X² = 27
E) X³ = 1024

Answer 1

A) x² =100

x=√100

x=10

B) X² =64

x=√64

x=8

c) X² = 1600

x=√1600

x=40

D) X² = 27

x=√27

fatora

x=√3².3

x=3√3

E) X³ = 1024

x=∛1024

fatorando:

1024|2  

0512|2  

0256|2  

0128|2  

0064|2  

0032|2  

0016|2  

0008|2  

0004|2  

0002|2  

0001_= 2³·2³·2

x=∛2³.2³.2

x=2√16
