Roots represent another form of writing numbers in fractional (rational) power. This means the following expressions are equivalent

If n = 2, this index does not appear in the root but it is implied. We call it the square root of the number. On the other hand, when the index n = 3, we are dealing with the cubic root of the given number.

For example,

= 2

= 4

This result could have been obtained in a different way:

This is true because 4^{3} = 64.

The following rules are applied when multiplying and dividing two roots:

If the two roots have the same index (n_{1} = n_{2} = n), then

and

This is true because

and

For example,

Indeed,

Thus,

Another example,

Indeed,

Thus,

If the two roots have the same index (n_{1} = n_{2} = n), then

and

This is true because

and

For example, if n = 2, then

√**2**^{4} ∙ √**4**^{3} = √**2**^{4} ∙ 4^{3} = √**16 ∙ 64** = √**1024** = 32

Indeed,

√**2**^{4} = √**16** = 4 and √**4**^{3} = √**64** = 8

Thus,

√**2**^{4} ∙ √**4**^{3} = 4 ∙ 8 = 32

Another example,

Indeed,

√**10**^{6} = √**1,000,000** = 1000 and √**5**^{4} = √**625** = 25

Thus,

If the two roots have different indices m and n (m ≠ n), then

This is true because

and

This is true because

For example,

=

=

=

= 400

Indeed,

Thus,

Another example,

Indeed,

Thus,

Obviously, you don't have to make all these calculations. You just have to insert the numbers and the calculator will calculate the result automatically.
