Solution:

package main

import (
    "big"
)

func main() {
    strMap := make(map[string]int)
    for a := 2; a < 101; a++ {
        for b := 2; b < 101; b++ {
            bigA := big.NewInt(int64(a))
            bigB := big.NewInt(int64(b))
            bigA.Exp(bigA, bigB, nil)
            strMap[bigA.String()] = 0
        }
    }
    println(len(strMap))
}
