Answer 2

By rounding 49 to 50 and 138 to 100, both to one significant figure, the estimated multiplication result of 49 x 138 is 5,000.

Step-by-step explanation:

To estimate the answer to 49 x 138 by rounding to one significant figure, we first round each number to one significant figure. The number 49 rounds to 50 (since the first digit, 4, is followed by a 9 which rounds up) and 138 rounds to 100. These rounded numbers are now easier to multiply.

So, we calculate 50 times 100, which equals 5000. Therefore, the estimated answer to 49 x 138, after rounding to one significant figure, is 5,000.
