$$\sqrt{0.25} - \sqrt[3]{0.008} + \sqrt{0.36} + \sqrt[4]{0.0256}$$ = ?

Correct option is A

Given:
Expression: $$\sqrt{0.25} - \sqrt[3]{0.008} + \sqrt{0.36} + \sqrt[4]{0.0256}$$​​
Solution:
​$$\sqrt{0.25} - \sqrt[3]{0.008} + \sqrt{0.36} + \sqrt[4]{0.0256}$$​​
​$$= 0.5 - \sqrt[3]{0.008} + \sqrt{0.36} + \sqrt[4]{0.0256}$$​​
​$$= 0.5 - 0.2 + \sqrt{0.36} + \sqrt[4]{0.0256}$$​​
​$$= 0.5 - 0.2 + 0.6 + \sqrt[4]{0.0256}$$​​
= 0.5 - 0.2 + 0.6 + 0.4
= 0.3 + 0.6 + 0.4
= 0.9 + 0.4
= 1.3
Final Answer
So the correct answer is (a)
