When we multiply any number by 10 then at the end of the number there will be a 0.
What are digits?
In a positional numeral system, a numerical digit is a single sign that can be used singly or in combination to represent numbers.
A digit is a part of a set that, when combined, makes up a numeration system.
For example 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 are digits.
Let's suppose the number 456
Multiply it by 10
456 × 10 = 4560
Let's multiply it by 100
456 × 100 = 45600
So it is clear that the number of zeros at the end of a number depends upon whether it is 10, 100, or 1000, and so on.
Now,
19,340×10 in this one zero is already present so the number of zeros will be 2.
19,340×10 = 193400
19,340×100 in this one zero is already present so the number of zeros will be 3.
19,340×100= 1934000
19,340×1000 in this one zero is already present so the number of zeros will be 4.
19,340×1000= 19340000
Hence the number of zeros at the end of a number depends upon the value of zero in 10,100 and so on.
