125^2/3
Think of it like this cube root (125^2)
So square 125 which is 125*125 or 15625
Then take the cube root of that: 25.

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

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

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

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

Given Equation

$\boxed{ \tt \: (8 \sqrt{3} - 2 \sqrt{2} )(8 \sqrt{3} + 2 \sqrt{2})}$

Step by step expansion:

$\dashrightarrow \sf \: (8 \sqrt{3} - 2 \sqrt{2} )(8 \sqrt{3} + 2 \sqrt{2})$

$\\ \\$

$\dashrightarrow \sf \: (8 \sqrt{3})^{2} - (2 \sqrt{2} {)}^{2}$

Reason:

(a + b)(a - b) = a²- b²

$\\ \\$

$\dashrightarrow \sf \: (8 {}^{2} \times { \sqrt{3} }^{2} )- (2 \sqrt{2} {)}^{2}$

$\\ \\$

$\dashrightarrow \sf \: (64 \times 3 ) - (2 \sqrt{2} {)}^{2}$

$\\ \\$

$\dashrightarrow \sf \: (64 \times 3 ) - (2 {}^{2} \times \sqrt{2} {}^{2} {)}$

$\\ \\$

$\dashrightarrow \sf \: 192- 8$

$\\ \\$

$\dashrightarrow \sf \: 184$

$\\ \\$
