Consider the two equations $x^2 = 49$ and $x^3 = 8$ .
Which statement correctly describes their solutions?

$x^2 = 49$ has solutions $x = 7$ and $x = -7$ ; $x^3 = 8$ has the single solution $x = 2$ .

$x^2 = 49$ has the single solution $x = 7$ ; $x^3 = 8$ has the single solution $x = 2$ .

$x^2 = 49$ has solutions $x = 7$ and $x = -7$ ; $x^3 = 8$ has solutions $x = 2$ and $x = -2$ .

$x^2 = 49$ has the single solution $x = 7$ ; $x^3 = 8$ has solutions $x = 2$ and $x = -2$ .
