What’s the value of the discriminante -2x^2+3x+1

The value of the discriminante is 17. This means that the parabola has two real solutions because it is greater than 0.

Step-by-step explanation:

-2x^2+3x+1

discriminante formula = b^2-4ac

a= -2

b= 3

c= 1

3^2-4(-2)(1)

9+8

17

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)
