Question

What will be the number of zeroes in the square of the number $9000$?

• A. $2$
• B. $3$
• C. $9$
• D. $6$

Answer 1

The correct option is D $6$

Say $x=9000$ ........ (1)

On squaring both sides, we get

$x^2=(9000{)}^2$

$x^2=9000\times 9000=81000000$

Hence, there are $6$ zeroes in the square of $9000$.
