如何用Java编写此公式？

Question

I have tried to represent this formula in Java but the values are not correct maybe I have some issue transforming the formula to code.

private double getFactor(int y) {
    double factor = 10 * Math.pow(3, logOfBase(2, 10 + Math.pow(y, 3)));
    return factor;
}

public double logOfBase(int base, double num) {
    return Math.log(num) / Math.log(base);
}

Answer 1

What about splitting it into more parts:

double temp = (double)10 + Math.pow(0, 3); // 0 = y
double factor = 10 * Math.pow(Math.log(temp), 3); //Math.log - Returns the natural logarithm (base e) of a double value

System.out.println(String.valueOf(factor));

Answer 2

我认为您正在寻找的是对数3，而不是对数3的幂。因此，公式应为

double factor = 10 * logOfBase(3, 10 + Math.pow(y, 3)));

Answer 3

To go on Ben Win's for all values of y.

public double getfactor(int y){
double temp = (double)10 + Math.pow(y, 3); //
double factor = 10 * Math.pow(Math.log(temp), 3); 
return factor;
}
