Answer:

$y^6$

Step-by-step explanation:

$\frac{a^b}{a^c} = a^{b - c}$

Using this rule we have:

$\frac{y^{-7}}{y^{-13}} = y^{-7 -(-13)} = y^6$

Answer:

$y^6$

Step-by-step explanation:

The applicable rules of exponents are ...

$y^ay^b=y^{a+b}\\\\\dfrac{1}{y^{-a}}=y^a$

Using these rules, you can write the expression as ...

$\dfrac{y^{-7}}{y^{-13}}=y^{-7-(-13)}=y^6$

<h2>Explanation:</h2><h2 />

The complete question is shown in the figure below. As you can see one square units is well shown in the graph. So we can conclude that the distance between two consecutive points is 1 unit. If so, then we can calculate the area of the parallelogram as follows:

$A=b\times h \\ \\ A:Area \\ \\ b:Base \\ \\ h:Height \\ \\ \\ CB=b \\ \\ AB=h$
