Lim x⟶ 1 (x3 + 1 ÷ x2 - 1) = 1 + (x3 + 1) = 2 = 1 + (1 ÷ x2 - 1) = ∞ = 2 x ∞ =  1 - (x3 + 1 ÷ x2 - 1) = -∞ 

Lim x⟶ -1log (x2 + 1 ÷ x2 + 1) | -1 (log (x2 + 1 ÷ x2 + 1)) = 0 

Lim x⟶ 3 (in (√x + 1 - 2 ÷ x - 3)) = ∞

Lim x⟶ log (√x + 2 - 2 ÷ x) = 2 (√x + 2 - 2/x) = √2 + 2 - 2/2 = √3 = decimal: 1.73205...

Lim x⟶ 2 in (x2 - 2x ÷ x2 - 4x + 4) = ∞  = x2 - 2x /x2 - 4x + 4 = x/x - 2 = 2 + (x/ x - 2)  = 0 

Lim x⟶2 in ((x2 - 2x)3 - x6/ x2 - 4) = - 64
