√ ( X² + 4X - 4 ) = 2 - X
( √( X² + 4X - 4 ))² = ( 2 - X )²
X² + 4X - 4 = 4 - 4X + X²
4X + 4X = 4 + 4
8X = 8
X = 1
ОДЗ : X² + 4X - 4 ≥ 0 ; D = 16 + 16 = 32 ; √ 32 = 4√2
X1 = ( - 4 + 4√ 2 ) : 2 = - 2 + 2√2 ; X2 = ( - 2 - 2√ 2 )

∛ ( 5X - 17 ) = - 3
( ∛ ( 5X - 17 ))³ = ( - 3 )³
5X - 17 = - 27
5X = - 10
X = - 2
