Find Five digit Cube and cube root Tricks


 


Need to remember 1 to 10 cube and this so easy for any one.
 


Example 1:
3√13824 = ?
 


Answer :
 


Step 1: Last digit of cube number from right side is 4 that we consider 64 = 43 we put down 4. Then
 


Step 2: Take the number whose cube is nearest to 13.
That is 13 is nearest to 23 and 33 we take small one cube digit that is 2.3√13824


So the answer is 24.


 


Example 2:
3√15625= ?
 


Answer :
 


Step 1: Last digit of cube number from right side is 5 that we consider 125 = 53 we put down 5. Then
 


Step 2: Take the number whose cube is nearest to 15.That is 15 is nearest to 23 and 33we take small one cube digit that is 2.
So the answer is 25.


 


Example 3:
3√42875= ?
 


Answer :
 


Step 1: Last digit of cube number from right side is 5 that we consider 125 = 53 we put down 5. Then
 


Step 2: Take the number whose cube is nearest to 42.That is 42 is nearest to 33 and 43we take small one cube digit that is 3.
So the answer is 35.

Need to remember 1 to 20 cube and this so easy for any one.
 

Example 1:
3√3869893 = ?

Answer :
Step 1: Last digit of cube number from right side is 3 that we consider 343 = 73 we put down 7. Then
 

Step 2: Take the number whose cube is nearest to 3869.That is 3869 is nearest to 153and 163 we take small one cube digit that is 15.

3√3869893
So the answer is 157.


Example 2:
3√1728000 = ?
Answer :
Step 1: Last digit of cube number from right side is 0 that we consider 1000 = 103 we put down 0. Then
 

Step 2: Take the number whose cube is nearest to 1728.That is 1728 is nearest to 123and 133 we take small one cube digit that is 12.

3√3869893
So the answer is 120.
