ln2-ln1/2=ln2-ln(2的-1次方)=ln2+ln2=2ln2
ln(a的m次方)=m乘lna
ln(a的m次方)=m乘lna

ln2-ln1/2
=ln2-ln2^(-1)
=ln2+ln2
=2ln2.
=ln2-ln2^(-1)
=ln2+ln2
=2ln2.

ln2-ln1/2
=ln[2/(1/2)]
=ln4
=ln2^2
=2ln2
=ln[2/(1/2)]
=ln4
=ln2^2
=2ln2

In 2-In1/2,表述不是很清楚呀。
是(In2-In1)/2?还是In2-In(1/2)?
应该是后者吧?
如果是的话:
解1:
In2-In(1/2)
=In2-In[2^(-1)]
=ln2-(-ln2)
=2ln2
解2:
In2-In(1/2)
=In[2/(1/2)]
=ln(2×2)
=ln(2^2)
=2ln2
是(In2-In1)/2?还是In2-In(1/2)?
应该是后者吧?
如果是的话:
解1:
In2-In(1/2)
=In2-In[2^(-1)]

=ln(2×2)
=ln(2^2)
=2ln2
