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 =

9i

Step-by-step explanation:

hope this helps

9i

Step-by-step explanation:

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

-81 can be break into 81 times -1

that is 81  and -1

as per the product property

square root (-1) is 'i'

square root (81) is 9

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.
