Evaluate : ā27 + ā0.008 + ā0.064
Solution:
Given, the expression is ā27 + ā0.008 + ā0.064
We have to evaluate the expression.
ā27 = ā(3)³ = 3
ā0.008 can be written as ā(8/1000)
ā8 = ā(2)³ = 2
ā1000 = ā(10)³ = 10
So, ā0.008 = 2/10 = 0.2
ā0.064 can be written as ā(64/1000)
ā64 = ā(4)³ = 4
ā1000 = ā(10)³ = 10
So, ā0.064 = 4/10 = 0.4
ā27 + ā0.008 + ā0.064 = 3 + 0.2 + 0.4
= 3 + 0.6
= 3.6
Therefore, the required value is 3.6
