When calculating the pension obligation, we can calculate the Accumulated Benefit Obligation (ABO), the Vested Benefit Obligation (VBO), or the Projected Benefit Obligation (PBO). Assume 80% of pension benefits are vested. Choose the list below that shows the three options in descending order (highest to lowest).

O A ABO, VBO, PBO
O B PBO, VBO, ABO
O c VBO, PBO, ABO
o D PBO, ABO, VBO
O E VBO, ABO, PBO VBO, ABO, PBO

it happens during combustion and impacts the environment because the plants and trees take in that and it can cause them to die.

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)
