Question

Ex 10 va rog repedeeee va rooog

Answer 1

Scoatem de sub radical:

a)

$\sqrt{0,09} =0,3$

$\sqrt{0,0196} =0,14$

$\sqrt{576} =24$

Inlocuim si obtinem:

$\frac{4}{3}\cdot 0,3+\frac{15}{7}\cdot 0,14 +\frac{2}{3} \cdot 24=\\\\\frac{2}{5} +\frac{3}{10} +16=\frac{167}{10} =16,7$

b)

$\sqrt{0,0144} =0,12\\\\\sqrt{0,16} =0,4\\\\\sqrt{0,36} =0,6$

Inlocuim si obtinem:

$\frac{5}{2} \cdot 0,12-0,4+\frac{1}{6}\cdot 0,6=\\\\ \frac{3}{10}-\frac{4}{10}+ \frac{1}{10}=0$

c)

$\sqrt{0,0225}=0,15\\\\\sqrt{0,81} =0,9\\\\\sqrt{0,0324}=0,18$

Inlocuim si calculam cum am facut mai sus, la celalalte puncte

d)

$\sqrt{0,0289} =0,17\\\\\sqrt{\frac{196}{81} } =\frac{14}{9}$

$\sqrt{\frac{144}{256} }=\frac{12}{16} =\frac{3}{4}$

Inlocuim si obtinem:

$\frac{17}{5} : 0,17-\frac{14}{3}\cdot \frac{9}{14} -\frac{24}{9}\cdot \frac{3}{4}=\\\\ 20-3-2=15$
