$- 45 x^{6} y^{8}$ $-45x^6y^8$

Explanation:

$(- 9 x^{3} y^{4}) (5 x^{3} y^{4})$ $(-9x^3y^4)(5x^3y^4)$

$(- 9 \times 5) \cdot x^{3 + 3} \cdot y^{4 + 4}$ $(-9xx5)*x^(3+3)*y^(4+4)$

$- 45 x^{6} y^{8}$ $-45x^6y^8$

The answer is $- 45 x^{6} y^{8}$ $-45x^6y^8$ .

Explanation:

Simplilfy $(- 9 x^{3} y^{4}) (5 x^{3} y^{4})$ $(-9x^3y^4)(5x^3y^4)$

Gather like terms.

$- 9 \times 5 \times x^{3} \times x^{3} \times y^{4} \times y^{4}$ $-9xx5 xxx^3xxx^3xxy^4xxy^4$

Use product rule $a^{m} a^{n} = a^{m + n}$ $a^ma^n=a^(m+n)$

$- 9 \times 5 \times x^{3 + 3} \times y^{4 + 4}$ $-9xx5xx x^(3+3)xx y^(4+4)$

Simplify.

$- 45 \times x^{6} \times y^{8}$ $-45xx x^6xxy^8$

$- 45 x^{6} y^{8}$ $-45x^6y^8$
