Question

Simplify: (−3a3b) • (3a4b3)
−9a12b3
−9(ab)12
−9a7b4
−27a7b4

Answer 1

The correct answer is c

Answer 2

The correct option is C)
`-9a^(7)b^(4)`

Explanation:

Consider the provided expression.

`(-3a^3b)\cdot (3a^4b^3)`

Now use the property of exponent:
`a^m \cdot a^n =a^(m+n)`

`(-3a^3b)\cdot (3a^4b^3)`

`-9a^((3+4))b^((1+3))`

`-9a^(7)b^(4)`

Hence the simplified form of
`(-3a^3b)\cdot (3a^4b^3)` is
`-9a^(7)b^(4)`

Thus, the correct option is C)
`-9a^(7)b^(4)`
