From a group of 6 dogs and 8 cats, in how many ways can 2 dogs or 2 cats be selected

420

Step-by-step explanation

First, we have 6*5 permutations of doges and 8*7 permutations of cats.

So we have 6*5*8*7 permutations of 2 doges and 2 cats.

However, since order doesn't matter we divide that by 2*1*2*1.

Therefore 6*5*8*7/4 = 420

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)
