Converting Mixed Radicals to Entire Radicals

Square the coefficient, multiply it by the number under the radical, and put the whole thing under a radical to convert it to an entire radical.

finally someone who knows how to explain math clearly thanks this really really helped

[realmoe]

Thanks so much I got 85% on my math test without paying attention

[izzynica]

AMEN! teachers honestly dont know how to teach half of the time (math teachers) they rush through. these youtube teachers explain every single step i love it

[cheekymonkeygirl]

Omg. I cannot thank you enough! You made this bimbo so proud! ☺️😻 please make more examples with fourth, fifth and so forth to convert mixed radical to entire radical.

[lexisummers]

I am in love with ur writing. And the camera angle here is amazing

[kimieg]

Everything makes sense now, thank you :) It is mathemagically accurate.

The reason behind learning more from a video than a teacher is quite simple. In general, when coming to school one normally come with the mentality of seeing friends/clubs/activities, so they lose track of the real reasoning of coming to school. Therefore, one might lose concentration and miss a few crucial details. However, when a student watches a video, they come with the mentality of, "I want to learn". Thus processing more thought. In addition, classes aren't personal. They are (Cont.)

Meant for a wide range of people (est. 20-60+ people). Hence, the teacher will not focus on ONE'S PROBLEMS, but on a general problem of one's class. As a result, the teacher may not always reveal all hidden tips and tricks to solving problems. In conclusion, teachers who teach at schools aren't bad, it is circumstance that he won't always focus an individual without significant notification. Also, it is the mentality of an individual that holds back his learning process.

@SwingingGatesSince98 Did you watch the end of the video?

Looks like I don't even need to pay attention in class, cause this video is great! I learned how to do it in the first minute.

Your my hero bro! Saved my life on my exam!

@sweetpiggy14 if you're trying to convert 2root(54) to an entire radical - you need to write the 2 as a radical first...
- change the 2 into root(2^2) or root(4) - this makes it a radical without changing the value of the number
- now you have root(4) x root(54)
- multiplying the 4 and the 54 and put them under the same root - root(4 x 54)
- write as root(216)

@PhiPhiHaya If the coefficient is negative, then you've got a negative number. If you were to square the negative coefficient (turning it to a positive) and put it under the radical, your number would become positive... That can't happen... So your number will have to remain "negative root

Example: -2root(6) = -root(24)

Plus you can pause it and rewind if you need to.

thank you, so glad people do stuff like this on youtube

[cheekymonkeygirl]

One question though, when we get the square root, cube root and so forth of a number, that number comes out of the radical if we get a whole number, for instance, the square root of 16 is 4 and the 4 will not be under a radical because it is freed from suppression, but when we square, cubed, and so forth of a number such as 3 squared is 9 and 9 still will be under the radical. Why? ☺️

[mastergamer]

My teacher said to do something else

Example

3-5
Your are saying to out the 3 with square. Then, add the number the amount of times of the variable. So 3'2 is 9. Then you multiply the 9 and 5 and get 45. My teacher said to just multiple 5 once then 3 two times so it would be 5x3x3. And whatever it equals is the answer

Thank you so much, you have no idea how much this helps.
