find the cube root of the 15625 through estimation method step by step
Answers
Answer:
We know that if the digit 5 is at the end of a perfect cube numbe its cube root will have its unit place digit as 5 only. Therefore, the unit place digit of the required cube root can be taken as 5. 2 is smaller between 2 and 3. Therefore, 2 will be taken at the tens place of reqWe will make groups of three digits starting from the digit of the number 15625, as 15625.groups are 15 and 625.
Considering the group 625,
625 ends with 5. We know that if the digit 5 is at the end of a perfect cube numbe its cube root will have its unit place digit as 5 only. Therefore, the unit place digit of the required cube root can be taken as 5.
Taking the other group that is 15,
We know that, 2³=8 and 3³= 27
8 < 15 < 27
2 is smaller between 2 and 3. Therefore, 2 will be taken at the tens place of req. cube root.
Therefore; ³√15625 = 25
