Question

calculați..va roggggg​

Answer 1

a)

$\sqrt{3} (4 + \sqrt{6} ) - ( \sqrt{12} - \sqrt{18} ) + ( \sqrt{27} + 2 \sqrt{6} ) \div \sqrt{3} - ( \sqrt{8} + 3) = \\ = 4 \sqrt{3} + 3 \sqrt{2} - 2 \sqrt{3} + 3 \sqrt{2} + 3 + 2 \sqrt{2} - 2 \sqrt{2} - 3 = \\ = 2 \sqrt{3} + 6 \sqrt{2}$

b)

$( \sqrt{150} - 3 \sqrt{10} ) \div \sqrt{2} + ( \sqrt{45} - 5) - \sqrt{75} = \\ = \sqrt{75} - 3 \sqrt{5} + 3 \sqrt{5} - \sqrt{75} = \\ = 0$

c)

$( \sqrt{54} - \sqrt{24} ) \div \sqrt{3} - ( \sqrt{160} - \sqrt{40} ) \div \sqrt{5 } = \\ = \sqrt{18} - \sqrt{8} - \sqrt{32} + \sqrt{8} = \\ = 3 \sqrt{2} - 4 \sqrt{2} = \\ = - \sqrt{2}$
