$\sqrt{4 - \sqrt{1} }$​

Answer 1

Resposta:

A) 11^(1/2)

B) 21^(1/2)

C) 53^(1/2)

D) 94^(1/2)

E) 3^(1/2)

Explicação passo-a-passo:

A)

[9 + 4^(1/2)]^(1/2) =

[9 + 2]^(1/2) =

[11]^(1/2)

B)

[25 - 16^(1/2)]^(1/2) =

[25 - 4]^(1/2)

[21]^(1/2)

C)

[49 + 16^(1/2)]^(1/2)

[49 + 4]^(1/2)

[53]^(1/2)

D)

[100 - 36^(1/2)]^(1/2) =

[100 - 6]^(1/2) =

[94]^(1/2)

E)

[4 - 1^(1/2)]^(1/2) =

[4- 1]^(1/2)

[3]^(1/2)
