It depends on the number taken.... For eg.---> 10....10×10=100( 2 zeroes), 100.....100×100=10000( 4 zeroes)... The no. of zeroes in the outcome is the double of the no. of zeroes present in the number which you have squared.........In the eg. 10 has 1 zero so its square contains double of its zero( 2 zeroes), same is with 100.
