Evaluate the expression:
(4 x 5)² - 6 + 3

397

Step-by-step explanation:

((4)(5))^2−6+3

397

4 x 5= 25²= 625 - 6 = 619 + 3 = 622

idk

step-by-step explanation:

maybe try   if it is work from a book, if not try

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)
