Answer 1

Respuesta:

d) 30

Explicación paso a paso:

A = 126 - (42 + raiz(5+4))

A = 126 - ( 42 + raiz(9))

A = 126 - (42 + 3)

A = 126 - 45

A = 81

B = 24 - (raiz(4)+3)

B = 24 - (2 + 3)

B = 24 - 5

B = 19

raiz(raiz(A) + 3B - 30

raiz(raiz(81)) + 3(19) - 30

raiz(9) + 57 -  30

3 + 57 - 30

60 - 30

30
