Answer: last option

Step-by-step explanation:

To solve this problem you must apply the properties of the exponents. WHen you have two powers with equal base, you must add the exponents.

Then you have:

[tex](6a^{2}b^{3})(-3a^{5}b^{3})=-18a^{(2+5)}b^{(3+3)}=-18a^{7}b^{6}[/tex]

Therefore as you can see, the coefficient is -18

Answer:

-18

Step-by-step explanation:

Question says to multiply [tex]6a^2 b^3[/tex] and [tex]-3a^5 b^3[/tex].

to find the product of the coefficients. And select correct choice from given list:

3

-3

18

-18

Coefficient of [tex]6a^2 b^3[/tex] is 6

Coefficient of [tex]-3a^5 b^3[/tex] is -3

Then product of coefficients = (6)(-3)=-18

Hence -18 is correct choice.
