Answer 1

[AI-generated answer — Bot GPT 3.5]

First, let's expand the multiplication:

(3y^4 + 5)(5y^7 + 4) = 3y^4 * 5y^7 + 3y^4 * 4 + 5 * 5y^7 + 5 * 4
= 15y^11 + 12y^4 + 25y^7 + 20

Now, let's simplify by combining like terms:

= 15y^11 + 25y^7 + 12y^4 + 20

Therefore, the simplified form of (3y^4 + 5)(5y^7 + 4) is 15y^11 + 25y^7 + 12y^4 + 20.
