Oblicz:
a) (4^1/2+3^1/3)^2
b) (a^-1/2-4) *(a^-3/2+a^-2+1)
a) (4^1/2+3^1/3)^2 = (√4 + ∛3)² = (2 + ∛3)² = 4 + 4∛3 + ∛(3²) = 4 + 4∛3 + ∛9
b) (a^-1/2 - 4) *(a^-3/2 + a^-2 + 1) =
a^-1/2 * a^-3/2 + a^-1/2 * a^-2 + a^-1/2 - 4a^-3/2 - 4a^-2 - 4 =
a^-2 + a^-5/2 + a^-1/2 - 4a^-3/2 - 4a^-2 - 4 = a^-5/2 + a^-1/2 - 4a^-3/2 - 3a^-2 - 4 =
