Question 144
Numbers $a$, $b$, $c$ satisfy the conditions:
$$
a^2 + 2 = b^4, \quad b^2 + 2 = c^4, \quad c^2 + 2 = a^4.
$$
What values can take expression
$(a^2 - 1)(b^2 - 1)(c^2 - 1)$?
$$
a^2 + 2 = b^4, \quad b^2 + 2 = c^4, \quad c^2 + 2 = a^4.
$$
What values can take expression
$(a^2 - 1)(b^2 - 1)(c^2 - 1)$?
