Best answer
Correct Answer - Option 1 : - 0.36

Given:

(0.25)1/2 + (0.0016)1/2 + (0.027)1/3 - (1.44)1/2

Formula Used:

Calculation:

(0.25)1/2 + (0.0016)1/2 + (0.027)1/3 - (1.44)1/2 

⇒ ((0.5)2)1/2 + ((0.04)2)1/2 +((0.3)3)1/3 +((1.2)2)1/2 

⇒ 0.5 + 0.04 + 0.3 - 1.2

⇒ 0.84 - 1.2

∴ The value of (0.25)1/2 + (0.0016)1/2 + (0.027)1/3 - (1.44)1/2 is -0.36
