Question

When 6a^2 b^3• -3a^5 b^3 multiplied, the product of the coefficients is .

3
-3
18
-18

Answer 1

-18

Explanation:

Question says to multiply
`6a^2 b^3` and
`-3a^5 b^3`.

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

3

-3

18

-18

Coefficient of
`6a^2 b^3` is 6

Coefficient of
`-3a^5 b^3` is -3

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

Hence -18 is correct choice.

Answer 2

Answer: last option

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:

`(6a^(2)b^(3))(-3a^(5)b^(3))=-18a^((2+5))b^((3+3))=-18a^(7)b^(6)`

Therefore as you can see, the coefficient is -18
