а) (∛6+∛30) ∛36 = (6^(1/3) + 30^(1/3)) 36^(1/3)Расскроем скобки:= 6^(1/3) 36^(1/3) + 30^(1/3) 36^(1/3)= 6^(1/3) 6 + 30^(1/3) 6= 6 + 30= 36
б) ∛12 - √19 ∛12 + √19 = 12^(1/3) - 19^(1/2) 12^(1/3) + 19^(1/2)= 12^(1/3) - 12 19^(1/2) + 19^(1/2)= 12^(1/3) - 12 19^(1/2) + 19^(1/2)= 2 - 12 * √19 + √19= 2 - 11√19.
а) (∛6+∛30) ∛36 = (6^(1/3) + 30^(1/3)) 36^(1/3)
Расскроем скобки:
= 6^(1/3) 36^(1/3) + 30^(1/3) 36^(1/3)
= 6^(1/3) 6 + 30^(1/3) 6
= 6 + 30
= 36
б) ∛12 - √19 ∛12 + √19 = 12^(1/3) - 19^(1/2) 12^(1/3) + 19^(1/2)
= 12^(1/3) - 12 19^(1/2) + 19^(1/2)
= 12^(1/3) - 12 19^(1/2) + 19^(1/2)
= 2 - 12 * √19 + √19
= 2 - 11√19.
