Question

how to find the cube root of any number give me detailed explanationplzzz​

Answer 1

Answer:

Now, the common thing here is that each ones digit of the cube numbers is the same number that is getting cubed , except for 2 ,8 ,3 ,7 .

now let us take a cube no like 226981 .

to see which is the cube root of that number , first check the last 3 digits that is 981 . Its last digit is 1 so therefore the last digit of the cube root of 226981 is 1 .

Now for the remaining digits that is 226

Now 226 is the nearer & bigger number compared to the cube of 6 (216)

So the cube root of 226981 is 61

Let us take another example - 148877

Here 7 is in the last digit but the cube of seven's last digit is not seven. But the cube of three has the last digit as 7.

So the last digit of the cube root of 148877 is 3.

Now for the remaining digits 148.

It is the nearer and bigger than the cube of 5 (125).

Therefore the cube root of 148877 is 53.

Answer 2

For example

the number is 1728

we have to find the cube root

statement will be 3√1728. (read it as cube root of 1728)

now take LCM of 1728

_2_ |_1728_

_2_ |_864_

_2_|_432_

_2_|_216_

_2_|_108_

_2_|_54_

_3_|_27_

_3_|_09_

_3_|_03_

_1_|_01_

LCM of 1728=2*2*2*2*2*2*3*3*3

pair =2*2*3=12

ANSWER=12

cube root of 1728 is 12

that's how you can find cube root
