Asap plz! i need answer under 5 mins! math betty and tina picked 9 coconuts from the island. they decided they would try to split them as fairly as possible. betty said she would take the 5 lightest coconuts and tina would have the rest. who has more coconut, by weight, and by how much more? tina had 3/4 lb more coconut than betty. betty has 3/4 lb more coconut than tina. betty has 1 1/4 lb more coconut than tina. tina has 1 1/4 lb more coconut than betty.

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)
