Let the coefficient by 'x'
Hence
its square root is x^(1/2) or x^(0.5)
Then the square root again is [x^(1/2)]^(1/2)
Third time over {[x^(1/2)]^(1/2)}^(1/2)
Now the rules of indices are
[x^(n)[^(m) = x^(nm) When terms are 'nested' , multiply together.
Also
x^(n) X x^(m) = x^(n+m)
x^)n) / x^(m) = x^(n-m)
However, the first rule (nesting) applies in this case, when you multiply the indices together/
Hence x^(1/2 X 1/2 X 1/2) = x^(1/8) , Which is the 8th root.!!!!!
