​$$\text{The value of } \sqrt{324} + \sqrt{0.0324} - \sqrt{5.29} =$$​​

Correct option is D

Given:

​$$\sqrt{324} + \sqrt{0.0324} - \sqrt{5.29}$$

Solution:

​$$\sqrt{324} + \sqrt{0.0324} - \sqrt{5.29}$$

=​$$\sqrt{324} + \sqrt{\frac{324}{10000}} - \sqrt{\frac{529}{100}}$$

= 18 + $$\frac{18}{100}-\frac{23}{10}$$

=18 + 0.18 - 2.3

= 18.18 - 2.3 = 15.88
