public static void main(String[] args)
	{
		
		double tenLog = getTenLog( 2, 3, 0.00001 );
		System.out.println(tenLog + "^" + tenLog + "=" + Math.pow(tenLog, tenLog));

	}
	
	public static double getTenLog( double min, double max, double precision )
	{
		double mid = ( min + max ) / 2;
		double ten = Math.pow(mid, mid);
		if ( Math.abs(ten - 10.0) <= precision )
		{
			return mid;
		}
		if ( ten > 10.0 )
		{
			return getTenLog( min, mid, precision );
		}
		
		return getTenLog( mid, max, precision );
			
	}

二分法啊…2.5开始，算出来比十大的话用2.25，不然用2.75以此类推…具体实现百度一下就好
