How do you simplify #4r^-3*2r^2# and write it using only positive exponents?

Answer 1

It is #8/r#

When you multiply the terms you will get #8r^-1# or #8/r#.

You simply multiply 4 by 2 and then add -3 and 2 (on rs).

Answer 2

To simplify (4r^{-3} \times 2r^2) and write it using only positive exponents, you can follow these steps:

  1. Multiply the coefficients: (4 \times 2 = 8).
  2. Add the exponents of (r): ((-3 + 2) = -1).
  3. Write the result with positive exponent: (8r^{-1}).

So, (4r^{-3} \times 2r^2) simplifies to (8r^{-1}).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
