Using the estimation method, find 3√32768. Group from the right: 32 | 768. Units of root from 768 (ends 8 - root ends 2). Tens: largest cube

Question

Using the estimation method, find 3√32768. Group from the right: 32 | 768. Units of root from 768 (ends 8 -> root ends 2). Tens: largest cube <= 32 is 27 = 3^3, so tens digit 3.

Accepted Answer

32. Tens digit 3 (since 3^3 = 27 <= 32 < 64), units 2 (cube ends in 8). 3√32768 = 32, and 32^3 = 32768.

Using the estimation method, find $332768$ .
Group from the right: 32 | 768. Units of root from 768 (ends 8 -> root ends 2). Tens: largest cube <= 32 is $27 = 3^{3}$ , so tens digit 3.
