Answer 2

The correct answer is $40a^{7} b^{4}$.

Given: The term = $5a^{2} b*8a^{5}b^{3}$.

To Find: The multiplication value of the term.

Solution:

$5a^{2} b*8a^{5}b^{3}$

= $40a^{2} b*a^{5}b^{3}$

Now add powers of a taking base a and add powers of b taking base b.

= $40a^{2+5} b^{1+3}$

= $40a^{7} b^{4}$

Hence, the answer is $40a^{7} b^{4}$.
