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}.

gregori [183]
A number (we don’t know the number so I’ll use X) plus five. So we can start the equation of with X+5 then divided by 3=7 so X+5➗3=7 so to solve what X is we can just go in reverse. 7 TIMES 3= 21-5=16 so X=16

omeli [17]

Answer:

pls show what is the following

Step-by-step explanation:

how to find it by yourself:

The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side. ... In other words, as soon as you know that the sum of 2 sides is less than (or equal to) the measure of a third side, then you know that the sides do not make up a triangle.
