Text Solution

Verified by Experts

`21.6002 |22
234|234
2732.10| 2732
2988
The three numbers are arranged with their decimal points aligned (shown on the left part above). The column juist left to the decimals has 4 as the doubtful digit. Thus, all thenumbers are rounded to this comumn.
The required expression is `2988xx13=38844.` S 13 has onlly tow significant digits the product should be rounded off after two significant digits. Thus the result is 39000.
