Given the polynomial below, which shows the terms in standard form??

5m^2n+9n^3-mn^2+2m^3

a. 2m^3+9n^3+5m^2n-mn^2

b. 9n+5m^2n+2m^3-mn^2

c. 2m^3+5m^2n-mn^2+9n^3

d. 9n^3-mn^2+5m^2n+2m^2

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:

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
