D = 10^5 x (10^-3)^4

D = 10^5 x 10^-3x4

D = 10^5 x 10^-12

D = 10^5+(-12)

D = 10^5-12

D = 10^-7

E = 10 x (10^-7)^3 x 10^9

E = 10 x 10^-7x3 x 10^9

E = 10 x 10^-21 x 10^9

E = 10^1+(-21)+9

E = 10^1-21+9

E = 10^-11

F = 2^3 x 5^3 x 10^8

F = (2 x 5)^3 x 10^8

F = 10^3 x 10^8

F = 10^3+8

F = 10^11

G = 10^-2 x 10^-7 / 10^6

G = 10^-2+(-7) / 10^6

G = 10^-2-7 / 10^6

G = 10^-9 / 10^6

G = 10^-9-6

G = 10^-15
