Tricks 3

In such
cases, n zeros are put at the right end of N to get a new number M and then M
is divided by 2

^{n}to find the required result of multiplication.
EXAMPLE;
FIND THE VALUE OF 9482*25

SOL. HERE N=
9482, 5

^{n }=25=5^{2}
Here n=2

According to
the rule ,

(N) (5

^{N}) (M)
9482*25=
948200/2

^{2}
=948200/4=237050

HERE n=2
hence two zeros are put.

M has been divided by 2^{2}as n=2
