Or y = a x

A> 1, which is an increasing function, 0.

so 3 0.8 > 3^0.7,0.75^-0. 1>； 0.75^0. 1, 1.0 1^2.7<； 1.0 1^3.5,0.99^3.3>； 0.99^4.5

Question 8 is also a simple drawing. I'll give you the result directly.

The steps are the same as in question 7.

( 1)m & lt； n(2)m & gt； n(3)m & gt； n(4)m & gt； n
