Question

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

Answer 1

Answer:

- 6r³.

Step-by-step explanation:

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

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

⇒ $P = (- 3) \times (2) \times r^{2}\times r$

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

⇒  $P = - 6 \times r^{2 + 1}$

{Using the property of exponent that $x^{a}\times x^{b} = x^{a + b}$}

⇒ P = - 6r³ (Answer)
