Name the property of congruence that justifies the statement: if ab cd then cd ab. (1 point). transitive property. symmetric property. reflexive property. none of these. i think its symmetric.

The Property of Congruence that justifies the statement: If AB CD then CD AB is Symmetric Property. The correct answer between all the choices given is the second choice. I am hoping that this answer has satisfied your query and it will be able to help you, and if you would like, feel free to ask another question.

i think the answer is b)

step-by-step explanation:

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
