Answer 2

Answer:

The correct option is A) $-8a^{7}b^{3}$.

Step-by-step explanation:

Consider the provided expression.

$(-2a^2b) \cdot (4a^5b^2)$

Now open the parentheses.

$(-2\times4)(a^2\times a^5)(b\times b^2)$

Now, use the product rule: $a^m \cdot a^n= a^{m+n}$

$(-8)(a^{2+5})(b^{1+2})$

$(-8)(a^{7})(b^{3})$

$-8a^{7}b^{3}$

Hence the simplified form of the provided expression is $-8a^{7}b^{3}$.

Therefore, the correct option is A) $-8a^{7}b^{3}$.
