Ineed learning how to solve -p-4p> -10

-p - 4p > -10

Combine like terms.

-5p > -10

Divide both sides by -5.

Because we multiplied by a negative, we must flip the sign.

p < 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)

answer is : muchas/tipicas

have a nice day!
