`a)6^3:6=6^(3-1)=6^2=36`

`b)3^5:32=3^5:2^5=(3/2)^5`

`c)`4^11:4^9=4^(11-9)=4^2=16` 

`d) `7^7:7^5=7^(7-5)=7^2=49`

`e)(-5)^5:(-5)^3=(-5)^(5-3)=(-5)^2=25`

`f)(-2)^9:(-2)^7=(-2)^(9-7)=(-2)^2=4`

`g)(-3)^3:(-3)^2=(-3)^(3-2)=(-3)^1=-3`

`h) 0,5^4:0,5^2=(0,5)^(4-2)=(0,5)^2=0,25`

`i)(3/2)^6:(-3/2)^3=(-3/2)^6:(-3/2)^3=(-3/2)^(6-3)=(-3/2)^3=-27/8` 

`k)(4/7)^5:(-4/7)^2=(4/7)^5:(4/7)^2=(4/7)^(5-2)=(4/7)^3=64/343`

`l)(-11/5)^8:(11/5)^7=(11/5)^8:(11/5)^7=(11/5)^(8-7)=11/5`

`m)(6/-7)^5:(6/7)^4=(-6/7)^5:(-6/7)^4=(-6/7)^(5-4)=-6/7`
