Question

Solve: 36a^4 b^10 - 81a^16 b^20 using GCF

Answer 1

Step-by-step explanation:

Um.. for your reference I have attached the answer here in written :)

GCF of 36 and 81 is 9.

GCF of a⁴b¹⁰ and a¹⁶b²⁰ is a⁴b¹⁰

So, answer is $\sf{ 9a^4 b^{10} (4 - 9a^4 b^{10})}$ .

Hope it helps :) Have a look at all the explanations in the attachment. :D

Answer 2

Answer:

9a^4b^10(2+3a^6b^5)(2-3a^6b^5) is your answer

Step-by-step explanation:

36a^4 b^10 - 81a^16 b^20

9×4a^4 b^10-9×9a^4×a^12×b^10×b^10

9a^4b^10(4-9a^12b^10)

9a^4b^10{2²-(3a^6b^5)²}

9a^4b^10(2+3a^6b^5)(2-3a^6b^5)
