Evaluate : ∛27 + ∛0.008 + ∛0.064

Solution:

Given, the expression is ∛27 + ∛0.008 + ∛0.064

We have to evaluate the expression.

∛27 = ∛(3)³ = 3

∛0.008 can be written as ∛(8/1000)

∛8 = ∛(2)³ = 2

∛1000 = ∛(10)³ = 10

So, ∛0.008 = 2/10 = 0.2

∛0.064 can be written as ∛(64/1000)

∛64 = ∛(4)³ = 4

∛1000 = ∛(10)³ = 10

So, ∛0.064 = 4/10 = 0.4

∛27 + ∛0.008 + ∛0.064 = 3 + 0.2 + 0.4

= 3 + 0.6

= 3.6

Therefore, the required value is 3.6
