Question

$(19000{)}^2$ will contain zeroes at the end.

• A. 3
• B. 4
• C. 5
• D. 6

Answer 1

The correct option is D 6

$(19\times 1000{)}^2$

$=19\times 19\times 1000\times 1000$

$=19\times 19\times 1000000\Rightarrow$ 6 zeroes

Alternate:
If a number ends with 'n' zeroes, its square ends with '2n' zeroes.
