Question

simplify 4 radical 20?

Answer 1

Firstly make the factors of 20.
Do it...

Answer 2

@waterineyes 1, 20, 2, 10, 4, 5 ?

Answer 3

No dear...

See, I give you one example then you will do that for 20.

See, I make the factors of 30..

I first divide it by 2, I get 15 as quotient..

So,

30 = 2*15

Now I divide 15 by 3, I get 5 as quotient..

So,

30 = 2*3*5

Now, 5 is not divisible by any other number..

So,

factors of 30 = 2*3*5

Now can you make the factors of 20???

Answer 4

@waterineyes 2 x 2 x 5

Answer 5

Yes dear you got it very much true..
Now this is in radical..
So, out of two same factors only one come out of radical..
I will give you the example..

40 = 2*2*2*5

Now, out of 2 two's one will go out of the radical..
