Answer 2

Let's break down the expression step by step:

$\frac{2^7}{3^7} - \frac{3^4}{5^4}$

First, simplify the fractions:

$\frac{128}{2187} - \frac{81}{625}$

Now, find a common denominator, which is the product of the denominators 2187 and 625:

$\frac{128 \times 625}{2187 \times 625} - \frac{81 \times 2187}{625 \times 2187}$

Simplify the numerators:

$\frac{80000}{1366875} - \frac{177147}{1366875}$

Combine the fractions:

$\frac{80000 - 177147}{1366875}$

Perform the subtraction in the numerator:

$\frac{-97147}{1366875}$

So, $\frac{2^7}{3^7} - \frac{3^4}{5^4} = \frac{-97147}{1366875}$.
