Question

What is the product of r^2 -3 and 2r

Answer 1

- 6r³.

Explanation:

Here, we have to find the product of r², - 3 and 2r.

Now, the product is, P = (r²)(- 3)(2r)

⇒
`P = (- 3) * (2) * r^(2)* r`

{Seperating each terms as the terms are in product form}

⇒
`P = - 6 * r^(2 + 1)`

{Using the property of exponent that
`x^(a)* x^(b) = x^(a + b)`}

⇒ P = - 6r³ (Answer)
