Solve the radical equation.
x+4= √x+10
what is the extraneous solution to the radical equation?

the solution -1 is an extraneous solution.
both -1 and -6 are true solutions.
the solution -6 is an extraneous solution.
neither -1 nor -6 is a true solution to the equation.

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)

step-by-step explanation:

only 10/60 isn't equivalent

hope this : )
