Вычислите: (49^(1/4)-25^(1/4))(49^(1/4)+25^(1/4)).

\[\left( 49^{\frac{1}{4}} - 25^{\frac{1}{4}} \right)\left( 49^{\frac{1}{4}} + 25^{\frac{1}{4}} \right) =\]

\[= \left( 49^{\frac{1}{4}} \right)^{2} - \left( 25^{\frac{1}{4}} \right)^{2} =\]

\[= \left( 7^{2} \right)^{\frac{1}{2}} - \left( 5^{2} \right)^{\frac{1}{2}} = 7 - 5 = 2\]
