若X的3K次方等于5,Y的2K次方等于3,则X的6K次方乘以Y的4K次方等于多少?
所以
X^(6K)*Y^(4K)
=[X^(3K)]²×[Y^(2K)]²
=5²×3²
=25×9
=225
X^(3K)=5,Y^(2K)=3 所以 X^(6K)*Y^(4K) =[X^(3K)]²×[Y^(2K)]² =5²×3² =25×9 =225...

设AC∩BD=O、D1B1中点为H、OH交ED1于G 连EO 因为ED1⊥面D1AC 所以ED1⊥D1O 设HG=x,在△D1B1E中 D1G/D1E=HG/B1E=D1H/D1B1=1/2 由ED1⊥D1O得 GD1^2 D1O^2=GO^2 D1E^2 D1O^2=EO^2 即5/4 1/4 x^2=(1 x)^2 ...
