Negative fractional exponent examples | Algebra I | Khan Academy

Missed the previous lesson?

Algebra I on Khan Academy: Algebra is the language through which we describe patterns. Think of it as a shorthand, of sorts. As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process. It's also seen as a "gatekeeper" subject. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. Without it, it's impossible to move forward. It's used by people with lots of different jobs, like carpentry, engineering, and fashion design. In these tutorials, we'll cover a lot of ground. Some of the topics include linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

i love the dude who makes these videos and I hope he knows these are highly appreciated

[Askarcher]

I like how he’s there to calm our anxiety in the begining 😂😂

This video really makes me look forward to seeing what will happen when radical is an odd number root, instead of even. Because then you won't have anything negative that can multiply to create that, since double negatives can't make a negative. Onward

Honestly, I love how he reminds the viewer to breathe, because I was absolutely overwhelmed, and I was very much forgetting to actually breathe. (/gen)

Thank you ..I understood negative fractional powers clearly..

[WoWdude]

u know ur in deep when ur staring at the screen at the beginning and whispering "please, sal.. help me out.."

What about negative base number with decimal exponents?
Something like -2^1.5
How will it work? Is it going to be a positive or negative answer?

What is the fractional exponent is not negative but the number is

[hannahprince]

This still doesn't solve my problem. I have an x raised to the -3/4. I have no idea what to do when. I get the whole -1/4 part, but what do I do with that 3? Is the entire fraction going to be raised to the 3 power? The x? The 4root? Help?

[SuTripeira]

This is probably really simple..but how do I solve the following equation?

V+12.11(V^-0.56)=48.66

My book says that the last example is ‘worth’ nothing.

They say the following:

(-8)^(1/3) = 3[square root]-8 = -2
But:
(-8)^(2/6) = 6[square root](-8)^2 = 2
Because 3 is even and 6 is uneven and (1/3) and (2/6) are worth the same, it “can’t” be right, therefore it is “worth” nothing.

I hate this because my calculator keep saying it’s -2, but my book says that negative bases aren’t allowed....

I’m so confused

[ashleyastudillo]

What would I do if it didn't have a parentheses ?

[williamchen]

wait, what if there were no brackets around the -27?

[pinky]

what would x raised to negative a half be equal to?
