   4^6(x^8)(y^-2) / 4^7(x^4)(y^2)
= 4^-1(x^4)(y^-4)
= x^4 / 4y^4

Therefore A is the correct answer. Obtained using exponent laws.

Laws used:
- Anything to the power of 0 is 1, which eliminates the base.
- When you divide like bases with exponents, you subtract the exponents to simplify.

Answer:

The area of the pentagon is = 31.5

Step-by-step explanation:

<em>First, we determine the perimeter of the "Pentagon" drawn in the attachment:</em>

p=4+4+4+4.5+4.5=21

<em>Now, we'll check the formula for pentagons:</em>

a=\frac{perimeter x apothem}{2}

<em>we calculate the apothem by placing a 90° angle in one of the sides of the shape. It is equal to:</em>

apothem=3

<em>then, we can substitute the values in the formula</em>

a=\frac{21(perimeter) x 3(apothem)}{2} =\frac{63}{2} =31 \frac{1}{2} or 31.5

Let me know if you have questions :D
