Answer 2

Sure, let's simplify the given expressions:

1. $16x \times 5y = (16 \times 5)xy = 80xy$

2. $-9x \times 7x^3 = (-9 \times 7)x \times (x \times x^3) = -63x^4$

3. $-7.2a^2b^3 \times (-10a^3b^4) = 72a^5b^7$

4. $x^2y^7 \times (-4x^3y^5) = -4x^{2+3}y^{7+5} = -4x^5y^{12}$

5. $-16x^3y \times 0.4x^5y^2 = 0$

6. $10.8 \times 4a = 43.2a$

7. $-10bc^3 \times 4a^2xc = -40a^2bc^4x$

8. $xy \times (-3xy^4) \times 4x^7y = -12x^{1+7+1}y^{1+4+1} = -12x^9y^6$

9. $-8ac^2 \times 4a^6 \times (-7c) = 224a^7c^3$
