First we find the square of 63.
63 is 13 greater than 50
soadd 13 to 25
it becomes 38.
Now square if 13 is 169 as we all know
so now 38+169
We will only add 1 to 8 and left all the remaining digits. it becomes 3969 which is the square of 63.now we are given to multiply 63 by 64 so add 63 to 3969.you will get 4032.
now multiply 4032 by 3 first. the answer is 12096.
Then multiply 12096 by 11
your final answer is 133056.
I Hope it may help you
