Question

encontre os valores de x nos itens ?

Answer 1

a) x^2 = 3^2 + 4^2

x^2 = 9 + 16

x^2 = 25

x = √25

x = 5


b) x^2 = 6^2 + 8^2

x^2 = 36 + 64

x^2 = 100

x = √100

x = 10


c) x^2 = (√10)^2 + (√15)^2

Cortando a raiz com o elevado ao quadrado

x^2 = 10 + 15

x^2 = 25

x = √25

x = 5


d) x^2 = (√60)^2 + 2^2

x^2 = 60 + 4

x = √64

x = 8


e) (√6)^2 = x^2 + (√2)^2

6 = x^2 + 2

x^2 = 6 - 2

x = √4

x = 2


f) (√26)^2 = x^2 + (√10)^2

26 = x^2 + 10

x^2 = 16

x = √16

x = 4
