Question

Evaluate: cube root of 0.027 + cube root of 0.008 + cube root of 0.064​

Answer 1

Answer:

0.027 = 27/1000

cuberoot 0.027 = (cuberoot 27)/cuberoot 1000

= 3/10 = 0.3

Using the same method,

cuberoot 0.008 = 0.2

cuberoot 0.064 = 0.8

cuberoot 0.027 + cuberoot 0.008 + cuberoot 0.064

= 0.3 + 0.2 + 0.8

= 1.3

Answer 2

Answer:

3√0.027 + 3√0.008 + 3√0.064

=0.03+0.002+0.04

=0.072
