Question

Determine valor de x=raiz de 21+raiz de 13+raiz de 7+raiz de 4 (as raízes são uma dentro da outra)

Answer 1

X = √21+√13+√7+√4
X = √21+√13+√7+2
X = √21+√13+√9
X = √21+√13+3
X = √21+√16
X = √21+4 = √25 = 5

Answer 2

Resposta:

x = √(21+√(13+√(7+√(4))))

x = √(21+√(13+√(7+√(4))))

x = √(21+√(13+√(7+2)))

x = √(21+√(13+√9))

x = √(21+√(13+3)

x = √(21+√16)

x = √(21+4)

x = √25

x = 5
