Answer 2

To simplify the expression $ab(-5ab^2)(4a^2b)$, you can use the distributive property of multiplication to multiply all the terms together:

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

Now, let's multiply the coefficients (numbers) and the variables separately:

Coefficients: $ab \cdot -5 \cdot 4 = -20ab$

Variables: $a \cdot a^2 \cdot a = a^{1+2+1} = a^4$ $b^2 \cdot b = b^{2+1} = b^3$

Now, multiply the coefficients and the variables back together:

$-20ab \cdot a^4 \cdot b^3$

So, the simplified expression is $-20a^5b^4$.
