Question

find the cube root by short cut method 103823 ​

Answer 1

Answer:

Here the units digit of 103823 is 3. If n

3

=103823, then the units digit of n must be 7. Let us split 103823 as 103 and 823. We observe that 4

3

=64<103<125=5

3

. Hence

40

3

=64000<103823<125000=50

3

.

Hence n must lie between 40 and 50. Since the units digit of n is 7, the only such number is 47. You may check that 47

3

=103823.

Answer 2

Answer: 47

Step-by-step explanation:

Divide 103823 in two parts. 103 and 823. Now, see units digit of 823 which is 3. It comes in cube of 7. Now, 103 lies between cube of 4 and cube of 5. Take the smaller number which is 4.

So, the number obtained is 47.
