To solve this we can factor the whole numbers then expand everything and finally combine the like terms
Let's take one term at a time
6^5 = 3^5 x 2^5
26 = 2 x 13
25^12 = 5^12 x 5^12
Now we can put everything together and see what we can combine
3^5 x 2^5 x 2 x 13 x 5^12 x 5^12
we can combine 2^5 x 2 to get 2^6 and we can combine 5^12 x 5^12 to get 5^24
So our final answer can be written this way
2^6 X 3^5 X 5^24 X 13
All of the number have been factored to their prime form and are to the correct powers.
