Pre-Algebra 30 - Rational Exponents

[@HainesHunters]

These videos are awesome. Clear, informative, easy to follow and very well put together. This are great for GRE prep!

at the minut 8:25 I got lost how we came from a2/3 - 1/6 to a4/6 - 1/6 = a3/6 do we multiplie with 2 to have 6 and 4 ore how ?

+Gigi Ventura To divide a number raised to an exponent by the same number raised to a different exponent, we subtract the exponent in the denominator from the exponent in the numerator. In this example the numbers are both "a" and the exponents are 2/3 and 1/6. To subtract 1/6 from 2/3 we must create a common denominator. (This is explained more fully in Why U Pre-Algebra Chapters 14 and 15.) We do this by multiplying both the numerator and denominator of 2/3 by 2 which gives us 4/6. Since they have the same denominators, we can then subtract 1/6 from 4/6 which gives us 3/6 or 1/2.

thank u for uploading this videos

[@matysambe8076]

umm...wat if u have a negative fractional exponent.. e.g-27^-(2/3)/ 27^-(1/3

[@clarianken4223]

hi! can we use radical sign to represent negative exponents??

[@rabbitchan2682]

thank you. You helped me alot!

How come its not a^1/3 instead of a^2/3 ?

[@bree1125]

I am trying to figure out questions with negative fractions that have fractional exponents when one number in the fraction is negative. I can't find a video on it anywhere!

Same

[@MyWhyU]

Give us an example.

[@РусскийПоцык-е2х]

@@MyWhyU just as example it's easy 1 - 4 -2 And it's the same number not two

[@РусскийПоцык-е2х]

@@MyWhyU also I'd love to see a video about the exponents with negative fractions

[@MyWhyU]

Do you mean "four to the negative one-half power"?

[@monsterslayersph8707]

This video is what I'm looking for!!!! It helped me a lot!..thank you

[@joshuapayne5368]

So helpful thank you!

Is there something like a first root where you have 1√8?

So is an irrational power impossible? Or does it just produce an irrational, hard to calculate, answer?

[@RussellMinecraft]

Wait what if you had a complex exponent o.O
