By the estimation method, 3√2197: the number ends in 7, so the units digit of the root is 3 (since 3^3 = 27 ends in 7). With the leading group giving tens digit 1, what is 3√2197?

Question

Accepted Answer

13. Ends in 7 -> units of root is 3; leading 2 (below 8) -> tens 1. So 3√2197 = 13, and 13^3 = 2197.

By the estimation method, $32197$ : the number ends in 7, so the units digit of the root is 3 (since $3^{3} = 27$ ends in 7).
With the leading group giving tens digit 1, what is $32197$ ?
