Here are the solutions to your problems:

Multiply the non-zero digits.
$$ 4 \times 4 = 16 $$
Add the total number of zeros from the original numbers to the result.
There are two zeros (one from 40, one from 40). $1600$ The product is: $\boxed{\text{1600}}$
1. Calculate $60 \times 300$
Multiply the non-zero digits.
$$ 6 \times 3 = 18 $$
Add the total number of zeros from the original numbers to the result.
There are three zeros (one from 60, two from 300). $18000$ The product is: $\boxed{\text{18000}}$
1. Calculate the square root of 102
Represent the square root of 102.
$$ \sqrt{102} $$
Calculate the approximate value.
Since $10^2 = 100$ and $11^2 = 121$ , the square root of 102 will be slightly greater than 10. $\sqrt{102} \approx 10.0995$ The square root of 102 is approximately: $\boxed{\text{10.10}}$
