Is the line through the points r(-1,3) and s(2,-7) parallel to the graph of the line given by the equation, 10x + 3y = 6? explain. a. yes, both lines are vertical. b. yes, both lines have the same slope. c. no, both lines have positive slopes that are not equal. d. no, both lines have negative slopes that are not equal.

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)
