Answer:
n=3
Step-by-step explanation:
64^(1/3)
Note that the exponent 1/3 given stands for the third root of the integer.
64^(1/3) =4
Check: 4 x 4 x 4 = 64
(By comparison of 64^(1/3) to 64^(1/n) means n= 3)
∜(64^(1/3)) =∜(4) = 1.41421356
The real number is
All the roots are:
1.41421356
1.41421356i
−1.41421356
−1.41421356i
4 is not a perfect 4th power.
