c) 66.1169*10^23

d) 7.5*10^7

e)482*10^-9

f)518*10^-9

g)569.65*10^22

h)343.6*10^-6

Step-by-step explanation:

a) 1.56*10^5+25*10^

=156*10^2+25*10^2

=181*10^2

b) 0.005*10^9+2.45*10^5

=50*10^5+2.45*10^5

=52.45*10^5

c) 6.4169*10^23+5.97*10^24

=6.4169*10^23+59.7*10^23

=66.1169*10^23

d)2.25*10^8-1.5*10^8

=7.5*10^7

e)1.8*10^-10 -500*10^-9

=18*10^-9-500*10^-9

*=482*10^-9^

f) 1.8*10^-+500*10^-9

=18*10^-9+500*10^-9

=518*10^-9

g) 5.97*10^24-7.35*10^22

=597*10^22-7.35*10^22

=569.65*10^22

h)5.6*10^-6-3.48*10^-9

=5.6*10^-6-348*10^-6

=343.6*10^-6
