Write in the form ‘n^th root of a’ in each of the following numbers.

1. (81)^1/4 2. (49)^1/2

3. (15)^1/5 4. (512)^1/9

5. (100)^1/19 6. (6)^1/7

1. (81)^1/4

In general, a^1/n is written as ‘n^th root of a’.

So, (81)^1/4 is written as ‘4^th root of 81’.

2. (49)^1/2

In general, a^1/n is written as ‘n^th root of a’.

So, (49)^1/2 is written as ‘square root of 49’.

3. (15)^1/5

In general, a^1/n is written as ‘n^th root of a’.

So, (15)^1/5 is written as ‘5^th root of 15’.

4. (512)^1/9

In general, a^1/n is written as ‘n^th root of a’.

So, (512)^1/9 is written as ‘9^th root of 512’.

5. (100)^1/19

In general, a^1/n is written as ‘n^th root of a’.

So, (100)^1/19 is written as ‘19^th root of 100’.

6. (6)^1/7

In general, a^1/n is written as ‘n^th root of a’.

So, (6)^1/7 is written as ‘7^th root of 6’.
