Factor 35b%5E8c%5E2 to get 5*7*b*b*b*b*b*b*b*b*c*c
Factor 7b%5E4c%5E8 to get 7*b*b*b*b*c*c*c*c*c*c*c*c
Factor 15b%5E9c%5E2 to get 3*5*b*b*b*b*b*b*b*b*b*c*c


Now highlight the unique terms. Remember, highlight the most frequent terms


5*7*b*b*b*b*b*b*b*b*c*c


7*b*b*b*b*c*c*c*c*c*c*c*c


3*5*b*b*b*b*b*b*b*b*b*c*c


Now multiply all of the highlighted terms:

3*5*7*b*b*b*b*b*b*b*b*b*c*c*c*c*c*c*c*c

Multiply and simplify

105b^9c^8
