​

Answer 1

Answer:

Cube root of 729 = 9

Step-by-step explanation:

estimation method:

first lets start dividing the number 729 into groups of 3 starting from the one's place. We only get one group, that's 729.

So the unit place of the square root will be 9 because the one's place of the group, 729, is 9. And since there are no more groups, we can assume the ten's place to be 0.

The final number will be 09, or 9.
