Question

X^4-1=0
How do I solve this
??????

Answer 1

The answer is x = 1

Explanation:

You have the equation
`x^(4)`-1=0 and below are the steps to complete
Step 1:
`x^(4)`-1 = 0
Step 2: +1 =+1
Step 3:
`x^(4)` = 1
Step 4:
`\sqrt[4]{x^4}`=
`\sqrt[4]{1}`
Step 5: x = 1

The First step shows to undo subtraction and add instead.
The Second Step shows 0 adding to 1.
The Third step shows how we have to square root it with 4 instead of 2.
The Fourth step shows the same thing to both sides.
The Fifth step leads the answer to be 1.

Then if we plug in 1 replacing x the equation will be true
