The answer choices are yes, no or there is not enough information to say ( help me plzz)

Hi, I'm new can I get marked as brainlieser? It would be highly appreciated.

Hope my answer helps :)

lets get into answering your question.

Step-by-step explanation:

first to determine if 2 shapes are congruent, they MUST have the same sides or angles. Note: if a shape is flipped or resized it DOE NOT  mean it is NOT congruent.

okay so the bottom of both shapes is 5 and their sides are 7 so YES they are congruent.

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)
