Answer 2

It seems like you want to simplify the expression: -2a^7b * (-3)a^4b^9.

To simplify this expression, you need to apply the rules of exponents. When multiplying terms with the same base, you add their exponents. Let's break down the expression step by step:

-2a^7b * (-3)a^4b^9

First, multiply the constants: -2 * (-3) = 6.

Now, let's multiply the variables with the same base 'a':

a^7 * a^4 = a^(7+4) = a^11

Similarly, multiply the variables with the same base 'b':

b * b^9 = b^(1+9) = b^10

Now, the simplified expression is:

6a^11b^10
