Question

3^5 / 3^2 - 4^3 / 4^2 = ? *

Answer 1

Hello!

We have the expression:

$\frac{3^5}{3^2}-\frac{4^3}{4^2}$

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

1st fraction:

$\frac{3^5}{3^2}=3^5-3^2=3^{5-2}=3^3$

2nd fraction:

$\frac{4^3}{4^2}=4^3-4^2=4^{3-2}=4^1$

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

$3^3-4^1=(3\cdot3\cdot3)-4=27-4=23$

The result of this expression is 23.
