Hello!

We have the expression:

[tex]\frac{3^5}{3^2}-\frac{4^3}{4^2}[/tex]

The first step is to solve each fraction, then we can subtract it, look:

1st fraction:

[tex]\frac{3^5}{3^2}=3^5-3^2=3^{5-2}=3^3[/tex]

2nd fraction:

[tex]\frac{4^3}{4^2}=4^3-4^2=4^{3-2}=4^1[/tex]

Now, let's subtract the second value from the first value:

[tex]3^3-4^1=(3\cdot3\cdot3)-4=27-4=23[/tex]

The result of this expression is 23.
