[12343astronomer]

is there not a more simple way to do this?

[patrickJMT]

@12343astronomer well, i think many can just do this in their head

[nm2941]

this is way better than the explanation in my book

Hello

Not sure if you've covered this but I'm having difficulty with how to determine when to use absolute value signs when evaluating radical expressions. A topic on this would be helpful.

Your videos are great, btw.

Thanks for your efforts!

Three people are radicals... 

[rickschick777]

thanks.. a lot of help... the fog is slowly lifting ( but unfortunately still there) but i will figure it out... thanks...

@ss4vegeta92 it would be -12t

[MRxGWEEDO]

It should be the absolute value of x (making the answer 3|X|Z√(4)z all over y^3. dont forget the EiEiO test (even, even odd)

.

[ss4vegeta92]

how would u do this: √(-12t)^2

thanks in advance

[OutInTheWild194]

thanks! you're a great tutor!

[heavena2300]

I have a question.. how would u solve this problem

cube root of x to the sixth over cube root of 250...

I know .. I couldn't figure out how to write this in a math form...

Sorry.. +)

can you answer me ?
