Question

Am nevoie de ajutor!Cine poate sa faca a) c) e) si ex 4!!

Answer 1

Răspuns:

a)

$( - 3 \times \sqrt{100} + 2 \times \sqrt{144} \div \sqrt{36} ) \div \sqrt{169} = ( - 3 \times 10 + 2 \times 12 \div 6) \div 13 = ( - 30 + 24 \div 6) \div 13 = (6 \div 6) \div 13 = 1 \div 13 = 0.076$

c)

$( \sqrt{225} + \sqrt{169} ) \div ( - \sqrt{16} ) = (15 + 13) \div ( - 4) = - 28 \div 4 = - 7$

e)

$\sqrt{ {2}^{4} } \times \sqrt{ {3}^{2} } - \sqrt{ {5}^{2} } \times \sqrt{ {2}^{6} } + \sqrt{ {4}^{4 } } \times \sqrt{ {1}^{5} } = 2 \times 2 \times 3 - 5 \times 2 \times 2 \times 2 + 4 \times 4 \times 1 = 272$
