I was wondering what the answer of |1-i| is.

which is also 1.4142

Step-by-step explanation:

To solve this the formula is...

| a+(b)i | = which equals...

From the equation we know that a=1 and b=-1 because the "i" is negative

Plug in numbers...

Solve... you would get

This equals

Hope this helps!

step-by-step explanation:

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)
