Hello!
this problem comes with a slightly complex math equation that I had to ask my math teacher about, so I hope it helps.
<span>The expression n! means "the product of the integers from 1 to n"
</span>this can be said for any variable
say n is the total and r is the 2-letter combo
C(n,r<span>)=13!/</span>(2!(13−2)!)
If you use this equation, you will get a final answer of: 78
I hope this helps, and have a nice day.
Answer:
that's a lot I'm sorry but I can't do that all

sorrrryyyyy
Step-by-step explanation:
2/5+2/4 (find common denominator)
The common denominator is 20
2/5 is 8/20 (multiply by 4)
2/4 is 10/20 (multiply by 5)
8/20+10/20 is 18/20
If you simplify 18/20 this would by 9/10 if you divide by 2
so the total is 18/20 or 9/10 simplified
Hope this helps!!!!
Have a nice day :)

Step-by-step explanation:
<u>Radical Form and Exponent Form</u>
A radical can be expressed as a rational exponent following the identity:
![\displaystyle \sqrt[m]{x^n}=x^\frac{n}{m}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Csqrt%5Bm%5D%7Bx%5En%7D%3Dx%5E%5Cfrac%7Bn%7D%7Bm%7D)
We should also recall that:

We are given the expression:
