cube root is symbolized by ³√. Some examples are ³√8=2,  ³√1=1,  ³√216=6,   ³√343=7 .In this article best cube root finding trick provided for you.

For this trick you need to know

cube of 1 to ten (only thing you need to know)

1 to 10 cube table provided bellow

13	1
23	8
33	27
43	64
53	125
63	216
73	343
83	512
93	729
103	1000

TRICK:-

Taking example of   ³√1728

It is three step process

STEP 1:-

First consider last digit (8) and check which numbers cube last digit is 8.

We got Last digit 2 .

_2

STEP 2:-

Except last 3 numbers (728) take other numbers present

³√1728

Here only 1 present

Check 1 is which number cube

1³ =1

STEP 3:-

Taking another example it will clear to you:-

³√12167=

STEP 1:-

First consider last digit (7) and check which numbers cube last digit is 7.

We got Last digit 3 .

_3

STEP 2:-

Except last 3 numbers (167) take other numbers present

³√12467

Here only 12 is present

12 is not a perfect cube number

We take lesser number cube

Like :-3³=27 is grater than 12 and 2³ =8 is lesser than 12

We take 2

STEP 3:-

Combine 1^st and 2^nd step we get 23

³√12167=23

Another example:-

³√97336=

STEP 1:-

First consider last digit (6) and check which numbers cube last digit is 6.

We get Last digit 6.

_6

STEP 2:-

Except last 3 numbers (336) take another numbers present

³√97336

Here only 97 is present

97 is not a perfect cube number

We take lesser number cube

Like :- 5³=125 is greater than 97, 4³ =64 is lesser than 97

We take 4

STEP 3:-

Combine 1^st and 2^nd step we get 46

³√97336=46
