Usually, the root sign is the root indicating that a number is divided by 1 time.

For example:

√ x = 1 squared √x = x x) (1/2)

What about the derivative?

( 1/2) x ^( 1/2 - 1)

= ( 1/2) x ^( - 1/2)

= 1 / (2√x)

Another example is:

Y = a is the third power of the derivative, and Y = A (1/3).

y ' =( 1/3)a^( 1/3- 1)

Extending to the n power of a number can become 1 of the n power of a number.

In this way, it is easier to take the derivative.
