PreCalculus - Algebra Fundamental Review (5 of 80) Simplifying Square Roots & Exponents Ex. 2

In this video I will simplify more difficult algebraic expressions with radicals (square roots) and exponents.

Thanks for taking the time to share your mathematics knowledge. Keep them coming.

For the second to last one, can you also multiple the x^3 by ^-2 and then do the same for the denominator and then flip them to get the same result?

thankyou mr.van this helps me a lot dealing with differential calculus. some part of your lessons help me a lot

[hamids]

If I had a teacher like you I would A's my courses. You are amazing

[Sandysan]

You videos are my first source to brush up my math and physics knowledge. You are the best.

[JohnKramer]

in the first problem, why does the 4 not go with the x to the numerator, becoming 3x-4x^2-1?

[luigiguilli]

You should teach High school and undergraduate mathematics, more students would be inspired and motivated to join STEM fields.

[Chris_Cross-pfdp]

Sir in the 4th problem, why did you rearrange the variables? Does it matter what order they are in?

[mattphillips]

Is this Pre calculus or what you need to know in algebra before pre calculus?
Great videos, easy to follow and understand

[drablam]

thanks we really appreciate for your help.

[tysonburns]

I appreciate the sequencing of your precalculus videos, thanks for taking the time to put them together.

When would you need to use this? Some of my learners find it hard to understand ‘why’ this math exists and ‘why’ they have to learn it in school. Could you please help explain the application of this skill?

Thank you,

Thank you very much, really helped esp with the moving of the exponents to create positives : )

[mohannayak]

sir its awesome for all student teacher and lecturers

[fibo]

Your work is truly inspiring. My highest regards.

[jeffersonmartinez]

great videos. thank you soo much for teaching. Your a remarkable person.

Can it be (xy^3/ 3 )^1/2 or is that wrong?

[dennyleo]

Let's make an example out of the first problem. But it's going to be like this instead: 3x negative squared over 4x negative squared. What do you do after we reciprocate them? Then, since they both have the same exponential value where do they go? In the numerator or in the denominator?
