Dod you mean

$= \frac{ {n}^{5} }{ {n}^{ - 2} } \times \frac{ {n}^{2 - 6} }{ {n}^{8} }$

$= {n}^{5 - ( - 2)} \times {n}^{2 - 6 - 8}$

$= {n}^{7} \times {n}^{ - 12}$

$= {n}^{7 + ( - 12)}$

$= {n}^{ - 5} = \frac{1}{ {n}^{5} }$

What is 5C3?<br> A. 35<br> B. 10<br> C. 14<br> D. 28

galben [10]

Answer: B. 10

-5C3 or 5 choose 3 refers to how many combinations are possible from 5 items, taken 3 at a time. To calculate combinations, we will use the formula nCr = n! / r! ... * (n - r)!, where n represents the total number of items, and r represents the number of items being chosen at a time.

-10 is the total number of all possible combinations for choosing 3 elements at a time from 5 distinct elements without considering the order of elements in statistics & probability surveys or experiments. The number of combinations for sample space 5 CHOOSE 3 can also be written as 5C3 in the format of nCr or nCk.

Step-by-step explanation: Hope this help :D
