c) No.
Work Step by Step
a)
$20000 = 2*10000 = 2*10^4$
$102000 = 1.02*100000 = 1.02 *10^5$
$4000000 = 4*1000000 = 4*10^6$
b)
$20000/2 = 2*10^4/2 = 1*10^4$
$102000/2 = 1.02*10^5/2 = .51 *10^5 = 5.1*10^4$
$4000000/2 = 4*10^6/2 = 2*10^6$
c)
The exponent does not get divided by 2. The number itself is divided by 2, not the exponent.
