For y=axny=ax^ny=axn, what should be plotted to obtain a straight line?
A
For positive uuu and vvv, log(uv)=logu+logv\boxed{\log(uv)=\log u+\log v}log(uv)=logu+logv.
B
The logarithm power rule is log(ur)=rlogu\boxed{\log(u^r)=r\log u}log(ur)=rlogu.
C
Plot logy\log ylogy against logx\log xlogx.
D
The model may be unsuitable.
