Homework Statement
Find the inverse of
y=x4
Homework Equations

The Attempt at a Solution
i tried y+4=x
replacing y with x,
x+4= y
and I am quite stuck because of the modulus sign.
do i go on with x+4=y or x4=y?
A modulus function, also known as the remainder function, is a mathematical function that returns the remainder after dividing one number by another. It is denoted by the symbol "%".
The inverse of a modulus function is a function that "undoes" the modulus operation. In other words, it takes the remainder and returns the original number that was divided.
To find the inverse of a modulus function, you can use the extended Euclidean algorithm. This involves finding the greatest common divisor between the original number and the modulus, and then using that to solve a linear congruence equation.
No, a modulus function can only have one inverse. This is because the modulus function is not a onetoone function, meaning that different inputs can produce the same output.
Finding the inverse of a modulus function is useful in various situations, such as in cryptography and error correction codes. It is also used in solving modular arithmetic equations and in finding solutions to linear congruences.
