What is the cube root of 474552..? You should find this without using calculator n explain...?
We r going to calculate cube root hence make a 1st group of 3 digits of given number from right side of given number & remaining digits keep as it is which is 2nd group.
Now given no. is 474552
Now 552 is 1st & 474 is 2nd groups.
Then check only unit digit of 1st group.which is 2.
Now find out a number from 0 to 9 which has a unit digit 2 after its cube..this no. is 8.bcoz cube of 8 is 512..
Here our unit digit of ans is confirmed..i.e. 8
Now take 2nd grop i.e. 474
Now find out number whose cube nearest to 474 & also less than 474..
The no. is 7 bcoz cube of 7 is 343 which is less & nearest to 474..
Here our 10th digit number is confirmed which 7..
Hence ans is 78.
