AB=AC in the triangle ABC. The points P, Q and R lie on the sides AB, BC and AC respectively, such that BP=CQ and BQ=CR.
1)Draw the figure with this information(optional).
2)Prove that triangle PBQ is congruent to triangle QRC.
3)Prove that QPR=QRP

answer:

You should think about it and do the problem

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)
