Question

помогите пожалуйстааа

Answer 1

$( sqrt{40} times {10}^{0.25} - 5 sqrt[4]{125} times {8}^{0.25}) times sqrt[4]{10} = (2 sqrt{10} times {10}^{0.25} - 5 times {5}^{ frac{3}{4} } times {8}^{0.25} ) times sqrt[4]{10} = (2 times {10}^{ frac{1}{2} + frac{1}{4 } } - 5 times {5}^{frac{3}{4} } times {2}^{ frac{3}{4} } ) times sqrt[4]{10} = (2 times {10}^{ frac{3}{4} } - 5 times {10}^{ frac{3}{4} } ) times sqrt[4]{10} = - 3 times {10}^{ frac{3}{4} } times {10}^{ frac{1}{4} } = - 3 times {10}^{ frac{3}{4} + frac{1}{4} } = - 3 times {10}^{ frac{4}{4} } = - 3 times 10 = - 30$
