Check if one integer is an integer power of another

Question

This is an interview question: \"Given 2 integers x and y, check if x is an integer power of y\" (e.g. for x = 8 and y = 2 the answer is \"true\", and for x = 10 and y = 2 \

Answer 1

Previous answers are correct, I liked Paul's answer the best. It's Simple and clean. Here is the Java implementation of what he suggested:

public static boolean isPowerOfaNumber(int baseOrg, int powerOrg) {
    double base = baseOrg;
    double power = powerOrg;

    while (base % power == 0)
        base = base / power;
    // return true if base is equal 1
    return base == 1;
}
