Answer 1

Salut!

Uite cum facem:

1. 0,890204 hm = x nm
nm = 10^-9 m
hm = 10^2 m

Deci, rescriem 0,890204 hm = 89,0204 m
89,0204 m = x nm => 89,0204 m * 10^9 = x nm =>
=> 89,0204 m  = 89,020,400,000 nm =>
=>  0,890204 hm =89 020 400 000 nm  (89,0204 miliarde de nm.)

2. 123456789 micro metri = x km
123456789 micro metri = km * 10^-6 = 123,456789km (mutam virgula 6 numere de la dreapta spre stanga)

3. 1 Gigametru (Gm) = 10^9 m => 4 083,7 cm^2 = x Gm^2 =>
=> 4 083, 7 cm^2 = 4 083,7 * 10^-19 = 0.00000000000000040837 Gm

4. 256 783,5 dam^2 = x dm^2
1 dam^2 = dm^2 * 10^4 => 256 783,5 dam^2 = 2 567 835 000 dm^2

5. 4 735 000 km^3 = x Mm^3
1 Mm^3 = 1*10^9 km^3 => 4 735 000 km^3 = 0.004735 Mm^3

6. 0,00234 mm^3 = x pm^3
1 mm^3 = 1 * 10^27 pm^3 => 0.00234 mm^3 = 234*10^22 pm^3

7. 5685s = x hr y min z sec
5685 / 60 = 94,75 min
75/100 = 3/4 min = 45 sec (z)
94 min - 60 = 34 min (y)
x = 1
5685s = 1hr 34 min 45 sec

8. 320 ms = 320/1000 s = 0.32 s

Unele au fost destul de grele, sper sa se inteleaga.
