Question

Divide................

Answer 1

D

Explanation:

2r divided by 12r 2 is 6r

Answer 2

For this case we must divide the following expression:

`\frac {12r ^ 2} {2r}`

We know that:

`\frac {12} {2} = 6`

By power division properties we have to:

`\frac {x ^ n} {x ^ m} = x ^ {n-m}`

So:

`\frac {12r ^ 2} {2r} = 6r ^ {2-1} = 6r`

So, we have to:

`\frac {12r ^ 2} {2r} = 6r`

Answer:

`\frac {12r ^ 2} {2r} = 6r`
