Answer:


(12a^3b^6c^5)/(3a^2b^4c^5)=4ab^(2)

Explanation:

Given


(12a^3b^6c^5)/(3a^2b^4c^5)

Required

Simplify


(12a^3b^6c^5)/(3a^2b^4c^5)

To solve this, we apply the following law of indices:


(m^x)/(m^y) = m^(x-y)


(12a^3b^6c^5)/(3a^2b^4c^5) becomes


(12)/(3)a^(3-2)b^(6-4)c^(5-5)


(12)/(3)a^(1)b^(2)c^(0)


c^0 = 1; So, we have


(12)/(3)a^(1)b^(2)*1

Finally,


4ab^(2)

Hence:


(12a^3b^6c^5)/(3a^2b^4c^5)=4ab^(2)
