Question

Look at the example below which shows how the product property of radicals is used to simplify a radical. square root (-36)= square root (36) square root (-1) = 6i Use the product property of radicals to simplify the following radical. square root -81 =

Answer 1

Answer:

9i

Step-by-step explanation:

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

$\sqrt{-81}$

-81 can be break into 81 times -1

that is 81  and -1

as per the product property

$\sqrt{-81} =\sqrt{81} * \sqrt{-1}$

square root (-1) is 'i'

square root (81) is 9

$\sqrt{-81} =\sqrt{81} * \sqrt{-1}$

$\sqrt{-81} =9* i$

$\sqrt{-81} =9i$

Answer 2

Answer:

9i
