Answer:

\frac{6}{k-6}

Step-by-step explanation:

First, we can factor all of the following equations to turn that weird, huge looking thing into \frac{(k+6)(k-6)}{(k-6)(k-10)} ÷ \frac{(k-6)^2}{k(k-6)} × \frac{6(k-10)}{k(k + 6)}. We know that division is simply multiplication by the reciprocal, so that whole equation will turn into \frac{(k+6)(k-6)}{(k-6)(k-10)} × \frac{k(k-6)}{(k-6)^2} × \frac{6(k-10)}{k(k+6)}. Now we can cancel out some values if they are both in the numerator and denominator, which will turn that still huge looking thing into \frac{6}{k-6} which is our final answer, as it cannot be simplified further.

Hope this helped! :)

(K^2-36/k^2-16k+60)/(k^2-12k+36/k^2-6k)*(6k-60/k^2+6k)

=[(k^2-6^2)/(k-6)(k-10)]*[k(k-6)/(k-6)^2][6(k-10)/k(k+6)

=(k^2-6^2)(k/(k-6)^2)(6/k (k-6)
=6(k^2-6^2)/(k-6)^2(k+6)

4. Represent the following sets in Roster form.
Phoenix [80]

The roster form of the given sets are:

(i) A = {1, 3, 5, 7, 9, 11, 13, 15, 17, 19}.

(ii) B = {1, 2, 3, 4, 5, 6, 7}.

(iii) C = {27, 64}.

(iv) D = {-1, 0, 1}.

The roster form of any set is the set with all elements of the set written in the set.

In the question, we are asked to represent the known sets in the roster form.

(i) A=The set of all odd natural numbers less than 20.

The set of all natural numbers, that is numbers after 1.

Odd numbers are numbers of the form 2n - 1.

Thus, the roster form is: A = {1, 3, 5, 7, 9, 11, 13, 15, 17, 19}.

Going similarly to the others, we will get:

(ii) B={y: y = n, n ∈ N, n ≤7}

Roster form is, B = {1, 2, 3, 4, 5, 6, 7}.

(iii) C = {x: x is a perfect cube, 8 < x < 125}

Roster form is, C = {27, 64}.

(iv) D= {x: x ∈ Z, -2 < x < 2}​.

The roster form is, D = {-1, 0, 1}.
