Can I get encrypt data from this expression?

While studying RSA, I saw this decryption form.

M = Cd mod N

If i know M,d,N, How Can I get C data from this expression?

Is there any solution?

    This is the RSA problem. You cannot obtain C unless you have the "other" exponent or the parameters are small enough that brute force or factoring are computationally feasible.
