63. Вынести общий множитель за скобки: 1) x^(1/2) + x; 2) (ab)^(1/3) + (ac)^(1/3); 3) y^(1/4) − y^(1/3); 4) 12xy^(1/2) − 3x^(1/2)y.

1) \(x^{1/2}+x=x^{1/2}(1+x^{1/2})\).

2) \((ab)^{1/3}+(ac)^{1/3}=a^{1/3}(b^{1/3}+c^{1/3})\).

3) \(y^{1/4}-y^{1/3}=y^{1/4}(1-y^{1/12})\).

4) \(12xy^{1/2}-3x^{1/2}y=3x^{1/2}y^{1/2}(4x^{1/2}-y^{1/2})\).
