Solve for m i need an answer am correct answer but be sure of your answer %100

m = 2 +3/4 n

Step-by-step explanation:

We need to isolate m

4m -3n =8

Add 3n to each side

4m -3n+3n =8+3n

4m = 8+3n

Divide each side by 4

4m/4 = (8+3n)/4

m = (8+3n)/4

m = 2 +3/4 n

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)
