The area enclosed between the curve y = log e ( x + e ) and the coordinate axes is

3.

The parabolas y2= 4x and x2= 4y divide the square re ion bounded by the linesx = 4, y = 4 and the coordinate axes. If S1, S2 S3 a e espectively the area of theseparts numbered from top to bottom, then S1: S2 : S3 is
