- First study following values,
2=8 , 8=2 , 3=7 , 7=3
Remaining digits are same , for example 1=1 , 4=4 etc...
2. Will explain with examples,
Example 1
³√5832 ?
i) First will write 5832 in to 5,832 (ie, consider 3 digits from right end)
ii) From the last 3 digits consider final digit. Here final digit is 2.If 2 is the value will write 8 instead of 2 as explained above.
iii) This value is the final digit of result, ie in this example 8 is the final digit of result
iv) So we got final digit of the result, we have to find out thefirst digit of the result
v) In question, digit 5 only remaining, so find which numbers cube is below 5, ie 13 = 1 is below 5
vi) So first digit of result is 1 , So the result is 18
³√5832 = 18
Example 2
³√19683 ?
i) 19683 = 19,683
ii) From the last 3 digits, last digit 3 will write in to 7 (as explained above). So 7 is the final digit of the result
iii) In qustion digits 19 only remaining , 23 =8 is below 19, so first digit of the result is 2.
iv) So the result is 27
³√19683 = 27
Example 3
Example 3
³√46656 ?
i) 46656 = 46,656
ii) last digit 6 will convert to 6, so final digit of the result is 6
iii) Remaining digits in the question is 46, 33 = 27 is below 46, so the first digit of the result is 3 , so the final answer is 36
³√46656 = 36
