The simplified expression is $\left(-\frac{5}{7}\right)^{17}$ .

Solution:

Given expression is $\left(-\frac{5}{7}\right)^{8} \cdot\left(-\frac{5}{7}\right)^{9}$ .

To simplify this expression:

$$\left(-\frac{5}{7}\right)^{8} \cdot\left(-\frac{5}{7}\right)^{9}$

Using exponent rule:

If the base of the product is same then add the powers of the bases.

$a^m \cdot a^n = a^{m+n}$

$$\left(-\frac{5}{7}\right)^{8} \cdot\left(-\frac{5}{7}\right)^{9}=\left(-\frac{5}{7}\right)^{8+9}$

$$=\left(-\frac{5}{7}\right)^{17}$

$$\left(-\frac{5}{7}\right)^{8} \cdot\left(-\frac{5}{7}\right)^{9}=\left(-\frac{5}{7}\right)^{17}$

The simplified expression is $\left(-\frac{5}{7}\right)^{17}$ .
