Answer 2

To solve the first equation $\frac{7^5}{7^3} \times x = \frac{7^7}{7^2} \times x$, we can simplify using the properties of exponents.

$\frac{7^5}{7^3} \times x = 7^{5-3} \times x = 7^2 \times x$

$\frac{7^7}{7^2} \times x = 7^{7-2} \times x = 7^5 \times x$

So, the equation simplifies to $7^2 \times x = 7^5 \times x$.

Since the bases are the same, the exponents must be equal:

$2 = 5$.

This is not true, so there is no solution to the first equation.

For the second equation $\frac{8^6x}{8^4x} = \frac{8^9}{8^5}$, we can simplify similarly:

$\frac{8^6x}{8^4x} = 8^{6-4} = 8^2$

$\frac{8^9}{8^5} = 8^{9-5} = 8^4$

So, the equation simplifies to $8^2 = 8^4$.

Again, since the bases are the same and the exponents are not equal, there is no solution to the second equation either.
