Simplify this expression

pishuonlain [190]

Answer:

After simplifying, the exponent of x is 33 and the exponent of y is 0

Step-by-step explanation:

For us to simplify, we bring the x base together and the y base together

Recall from the law of indices;

x^a/x^b = x^(a-b)

and x^a * x^b = x^(a + b)

We shall be applying these here

Let us bring the x terms together

we have these as;

x^8/x^14 * 1/x^-39 = x^( 8 - 14 -(-39))

= x^(8 + 39-14) = x^33

for y, we have it that;

y^-26/y^-5 * 1/y^-21

= y^(-26 -(-5) - (-21)

= y^-26 + 5 + 21 = y^0

Number of pillow cases to be made by Jenny = 3

Amount of fabric Jenny has = 14 feet

Each pillow case use same amount of fabric.

Amount of fabric used to make 1 pillow case =

$=\dfrac{\text{Amount of fabric}}{\text{Number of pillow cases}}\\\\=\dfrac{14\text{ feet}}{3}\\\\\approx 4.67\text{ feet}$

Thus, approximately 4.67 feet of fabric is required for one pillow case.
