What is 6P4<br> permutations and combinations

labwork [276]

Answer:

360

Step-by-step explanation:

Here we are required to find $_^{6}\textrm{P}_{4}$

It is a problem of Permutation and we must understand the formula for finding permutations.

The general formula for finding the permutation is given as below:

$_^{m}\textrm{P}_{n}=\frac{m!}{(m-n)!}$

Hence

$_^{6}\textrm{P}_{4}=\frac{6!}{(6-4)!}$

$_^{6}\textrm{P}_{4}=\frac{6!}{2!}$

Where

$m!=m\times(m-1)\times\(m-2)\times\cdot\cdot\cdot\codt\cdot3\times2\times1$

$6!=6\times5\times4\times3\times2\times1$

$2!=2\times1$

Hence

$_^{6}\textrm{P}_{4}=\frac{6\times5\times4\times3\times2\times1}{2\times1}$

$_^{6}\textrm{P}_{4}=6\times5\times4\times3$

$_^{6}\textrm{P}_{4}=360$

Express p in terms of q if

Irina-Kira [14]

$p=x^2+\dfrac{1}{x^2}\\\\p=\dfrac{x^4}{x^2}+\dfrac{1}{x^2}\\\\p=\dfrac{x^4+1}{x^2}\qquad(*)$

$q=x+\dfrac{1}{x}\\\\q=\dfrac{x^2}{x}+\dfrac{1}{x}\\\\q=\dfrac{x^2+1}{x}\qquad\text{square both sides}\\\\q^2=\left(\dfrac{x^2+1}{x}\right)^2\\\\q^2=\dfrac{(x^2+1)^2}{x^2}\qquad\text{use}\ \ (a+b)^2=a^2+2ab+b^2\\\\q^2=\dfrac{(x^2)^2+2(x^2)(1)+1^2}{x^2}\\\\q^2=\dfrac{x^4+2x^2+1}{x^2}\\\\q^2=\dfrac{x^4+1}{x^2}+\dfrac{2x^2}{x^2}\\\\q^2=\dfrac{x^4+1}{x^2}+2\qquad\text{subtract 2 from both sides}\\\\q^2-2=\dfrac{x^4+1}{x^2}\\\\\text{From (*) we have}\\\\\boxed{p=q^2-2}$
