Solve for n
-53 + n = -28

25

Step-by-step explanation:

-53 + n= -28

-53 + 53 + n = -28 + 53

n = 25

-81

Step-by-step explanation: -53 + n = -28

                                            = n = -53/-28

                                            = -81 as you should put the sign of the bigger no.

true? is that what you're asking or do you mean something else?

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)
