Question

The area of a square room can be expressed as 196x^12y^10z^6 square feet . Hajime is installing a wallpaper border along the perimeter of the room. What is the perimeter?

Answer 1

area = length time width

area square = side time side = (side)^2

area = 196x^12y^10z^6

(side)^2 = 196x^12y^10z^6

side = sqrt(196x^12y^10z^6)

side = (196x^12y^10z^6)^(1/2)

side = 14x^(12/2)y^(10/2)z^(6/2)

side = 14x^6y^5z^3

hope helped understandably easy
