Answer 1

Answer:

$27a^6b^8 + 63a^5b^8 - 25a^8b^8$

Step-by-step explanation:

Given

$9a^3b^6(3a^3b^2+7a^2b^2)-(5a^4b^4)^2$

Required

Simplify

$9a^3b^6(3a^3b^2+7a^2b^2)-(5a^4b^4)^2$

Open both brackets

$9a^3b^6*3a^3b^2+9a^3b^6*7a^2b^2-5a^4b^4*5a^4b^4$

This gives

$27a^6b^8 + 63a^5b^8 - 25a^8b^8$
