• C. $$3\frac{10}{13}$$
• D. ഇവയൊന്നും അല്ല

Answer 1

Answer:

$$13\frac{3}{10}$$

$\sqrt{20\frac25+30\frac{3}{10}+x}=(2\sqrt{2})^2$

$\sqrt{20\frac25+30\frac{3}{10}+x}=8$

$20\frac25+30\frac{3}{10}+x= 8^2=64$

$20+30+2/5+3/10+x=64$

$50+7/10+x=64$

$x=64-50-7/10$

$x=14-7/10$

$x=(140-7)/10$

$x=133/10$

$x=13\frac{3}{10}$
