उत्तर
We have to find the cube of 35 using column method. We have: \[a = 3 and b = 5\]
| Column I a3 |
Column II \[a = 3 \text{ and } b = 5\]
|
Column III \[3 \times a \times b^2\]
|
Column IV b3 |
|---|---|---|---|
|
\[3^3 = 27\]
|
\[3 \times a^2 \times b = 3 \times 3^2 \times 5 = 135\]
|
\[3 \times a^2 \times b = 3 \times 3^2 \times 5 = 135\]
|
\[5^3 = 125\]
|
| +15 | +23 | + 12 | 125 |
| 42 | 158 | 237 | |
| 42 | 8 | 7 | 5 |
Thus, cube of 35 is 42875.
