Question

√√√√(2)³ Find the value

Answer 1

We know that, the value of √  is 1/2 = 0.5
Now, the given equation is √√√√(2)³
Solution:
√√√√(2)³  =  √√√√2x2x2

               =  √√√√8


               =  √√√8 ⁰·⁵

               =  √√ (8 ⁰·⁵ ) ⁰·⁵

               =  √√ 8 ⁰·²⁵ 

               =  √ ( 8 ⁰·²⁵ ) ⁰·⁵

               =  √ 8 ⁰·¹²⁵

               =  (8 ⁰·¹²⁵ )  ⁰·⁵

               =  8 ⁰

               =  1
This is the answer to the given question. Hope it will help. Thanks.
