Question

Bunaa, puteti sa ma ajutati va rog cu exercitiul atasat cat de corect se poate, mulțumesc ​

Answer 1

Răspuns:

$\frac{13}{2}$

Explicație pas cu pas:

$\sqrt{\frac{225}{16} } : \sqrt{\frac{25}{4} } + 2\frac{1}{3} : \sqrt{0,(1)} - \sqrt{324} : \sqrt{3^{4} } =$

$= \frac{15}{4} : \frac{5}{2} + \frac{7}{3} : \sqrt{\frac{1}{9} } - \sqrt{\frac{324}{81} }$

$= \frac{15}{4} *\frac{2}{5} + \frac{7}{3} :\frac{1}{3} - \sqrt{4}$

$= \frac{3}{2} + \frac{7}{3} *3 - 2$

$= \frac{3}{2} + 7 - 2$

$= \frac{3}{2} + 5$

$= \frac{3+10}{2}$

$= \frac{13}{2}$

Answer 2

Răspuns:

Explicație pas cu pas:

√225/16 = 15/4

√25/4 = 5/2

2 1/3 = 7/3

0,(1) = 1/9

√1/9 = 1/3

√324 = 18

√3^4 = 3^2 = 9

__________

15/4 : 5/2 + 7/3 : 1/3 - 18 : 9

= 15/4*2/5 + 7/3 * 3/1 - 2

= 3/2 + 7 - 2

= 3/2 + 5

= 3/2 + 10/2

= 13/2
