Question

Radical expressions

Answer 1

\[\frac{ 8x^7y^8z }{ 20x^6y^3z }\]

Answer 2

Me and shadow did a TON of this a few weeks ago, but the class moves so quickly I can’t remember a whole lot. I know in division I subtract the exponents.

Answer 3

Yes, and so basically, since you're starting off, it's best to separate these into separate fractions and do one at a time:

\(\dfrac{8}{20} \cdot\dfrac{x^7}{x^6}\cdot\dfrac{y^8}{y^3} \cdot\dfrac{z}{z}\)

Answer 4

I'm certain you are able to easily reduce the numerical fraction to start with, right?

Answer 5

The two z’s do cancel out right?

Answer 6

Yes, because anything over itself equals 1.

Answer 7

It's best after that to start left and work right.

Answer 8

I may be wrong

Answer 9

Don't be afraid to post what you've done so far.

Answer 10

\[\frac{ 2xy^5 }{ 5 }\]

Answer 11

Looks good to me.
