If there were no rules then the world would be thrown into anarchy and crime would run rampant (think of the movie The Purge). There would be senseless killings and no one would be safe. <span />
<span>If the answer is of the form <span><span>(<span>nk</span>)</span><span>(<span>nk</span>)</span></span> , what is the minimum value of n-k?</span>
If you are trying to calculate, don't bother.
<span>The answer is 1. </span>
<span>Why, because the answer, i.e </span><span><span><span>(<span>nk</span>)</span><span>(<span>nk</span>)</span></span> , </span>will be a number, let us assume that the answer is c, a constant number, which can be written as -
<span><span>(<span>c1</span>)</span><span>(<span>c1</span>)</span></span><span> = </span><span><span>(<span>c<span>c−1</span></span>)</span><span>(<span>c<span>c−1</span></span>)</span></span>
So, answer is c-(c-1)=1.
<span>Basically any question of this form, will have the answer 1, you even don't have to solve the problem.</span>
