There is no definitive answer for an estimation, so you could come up with something around 35000. The actual product is 35061.....

I think it means to do the work and then estimate it. But it could also be estimate the divisor and dividend and then do the work after those two numbers are estimated.
To round to estimate the product of 38 x 2, you first round each number to a more manageable value. In this case, you can round 38 to 40 and 2 to 0. Then, multiply the rounded numbers together to get an estimate of the product. In this case, 40 x 0 = 0. So, the estimated product of 38 x 2 is 0.
25x80 < 28x87 < 30x90 --> 2000 < 28x87 < 2700?
60 x 50 = 3000
3 x 5 = 15
find each product
In your example, the easiest way to estimate the product would be to round each factor to the nearest 10, 100, 1,000 or whatever the factors are. So, for 6,893 * 556, round to 7,000 * 600 to get an estimate. Since both numbers are rounded up, you know your estimate will be high, but this is an easy way to get a close answer. To be specific here, 7,000 and 600 would be multiplied to get 4,200,000. You multiply the first digits together, and then add the total number of zeroes in each rounded number to your answer.
No, 3 is not a good estimate for 3.4 times 0.09. To estimate the product of 3.4 and 0.09, you can round each number to the nearest whole number, which would be 3 and 0 respectively. Multiplying 3 by 0 gives you 0, which is significantly different from the actual product of 3.4 times 0.09, which is 0.306.
