Answer 1

9i

Explanation:

hope this helps

Answer 2

9i

Explanation:

Use the product property of radicals to simplify the following radical.

`√(-81)`

-81 can be break into 81 times -1

that is 81 and -1

as per the product property

`√(-81) =√(81) * √(-1)`

square root (-1) is 'i'

square root (81) is 9

`√(-81) =√(81) * √(-1)`

`√(-81) =9* i`

`√(-81) =9i`
