Solution :
Given that the expression is :
This can be written as,
a). Therefore the exponent in the power of 10
= 0
b). Factors of 10 in
= 10 x 10 x 10
= 1000
=
So there are 3 factors of 10 in
c). If we compare the exponent of power of 10 in 1000 and factors of 10 in 1000, then both of them will be same.
But in part a), we are finding exponent in the power of 10 in the expression which is equal to 0. And in part b), we are finding the factor of 10 in 1000, which is equal to 3, as 10 x 10 x 10 = 1000.
d). The value of the expression is 6.
