Question

(4 √40 - 3 √80 + 10 √10) ÷ (-√20) va rog rapid dar vr cu explicatii

Answer 1

Răspuns:

$(8 \sqrt{10} - 12 \sqrt{5} + 10 \sqrt{10)} \div ( - \sqrt{20)}$

$(18 \sqrt{10} - 12 \sqrt{5} ) \div ( - \sqrt{20)}$

$\frac{18 \sqrt{10} - 12 \sqrt{5} }{ - \sqrt{20} }$

$\frac{2(9 \sqrt{10 } - 6 \sqrt{5}) }{ - 2 \sqrt{5} }$

$- \frac{9 \sqrt{10} - 6 \sqrt{5} }{ \sqrt{5} }$

$\frac{6 \sqrt{5} - 9 \sqrt{10} }{ \sqrt{5} }$

$\frac{(6 \sqrt{5} - 9 \sqrt{10} ) \sqrt{5} }{5}$

$\frac{30 - 9 \sqrt{50} }{5}$

$\frac{30 - 45 \sqrt{2} }{5}$

$\frac{5(6 - 9 \sqrt{2)} }{5}$

$6 - 9 \sqrt{2}$

sper ca te-am ajutat
