Thank you buddy for your job.

Sir, your teaching is very stylish indeed.....😍😍😍

excelent info

Please provide the link of your previous lecture in the description or the playlist link it will help a lot for new commmers

Excellent

Thanks. ❤❤❤

(3)(3)=9x2=18

(5)(5)=25x2=50

I like you being a teacher.

You're BADASS

Super Teacher!

division used division multiplication subtraction

This awsome but it good

That trees are really cool stuff.

square root used repeated factor number multiplication equation

at 11:48 I get -2.radical 3 for the answer.

8/2=/50+/18

I need to see some examples with variables in the root. Great help though

Why in the end of video, we do times to radical of 5?? Thanks

I want to know how you solve problem 5}♤,

1.5

3/3+6/3

square root same divided

/2+2/2

add subtract radical

5x

/49+1

(8)(8)=64x2=128

/50+/18

What do you do if you have no extra prime in the prime factor tree? Since if there was an extra, you put them as the radicand. But if there's no extra, what then? I'm trying to solve 2 times cube root of 27 and doing the prime factor tree of 27 is 9 times 3 and 9 becomes 3 times 3. Since it's the cube root, I need triplets. All the 3's in the prime factor tree of 27 has now become one and I have no more extra. Please help asap thank you!

9/3

square root is equivalent of 2

Sir , when we take another multiplication of these radicals it's getting another answer, I meant for an instance if we have √36, you got 6.6, but if we take 9.4 then our answers will be wrong, isn't it I meant 16.55 min part question

8/4

5/2

y everybody saying math is so fun?

/68

3/2

(4)(4)=16+2=18

/5

(8)(8)=64+4=68

4

y=1

I love mathematics, but I need someone to teach me deeply.

2x+y

/4

/18

potatoes, buckets of potatoes.

The square root of 32 is 16, you could’ve just done 16 because 16 + 16.

Why not provide a link to the videos you’re referencing. Not that difficult to do.

7/1

68=/68

/2

2xy

2

/16+2

8/4=/50+18

omit add positive sign not negative sign

(2)(2)

8/2

Why radicals as a denominator is not acceptable??

/50

Im in 9th d=grade right now I dont knowwwwwwwwwww

/3

2 4 6 8 9 10

1

math will be is when you know what you are doing

2x+3x

in what country the radical sign is written that way? so confusing.

divided

square root repeated equation

cannot be

hahahaha
