2x-5y-4=0求4x^2/32y^2=?2x-5y-4=0求4x^2/32y^2=?2x-5y-4=0求4x^2/32y^2=?2x-5y=44x^2/32y^2不对应该是4^x/32^y=2^2

2x-5y-4=0求 4x^2/32y^2=?
2x-5y-4=0求 4x^2/32y^2=?

2x-5y-4=0求 4x^2/32y^2=?
2x-5y=4
4x^2/32y^2不对
应该是4^x/32^y
=2^2x÷2^5y
=2^(2x-5y)
=2^4
=16

f(x)=x+1/x
f(-x)=-x-1/x=-(x+1/x)
即f(-x)=-f(x)
且定义域x≠0
关于原点对称
所以是奇函数
