If there are 6 x 10^9 people on the Earth and there is enough freshwater to provide each person with 8.79 x 10^5 L, how much freshwater is on the earth?

Multiply it out: 6 x 10^9 * 8.79 x 10^5
First, mulitply out the first part of both numbers:
6 * 8.79 = 52.74 = 5.27 * 10^1
Now multiply out the exponents of 10:
10 ^9 * 10^5 * 10^1 = 10^(9+5+ 1) = 10^15
Put it together: 5.27 * 10^15 L

6,000,000,000 x 879,000 = 5,274,000,000,000,000 L
or 52.74 x 10^14 L
or
(6 x 10^9) x (8.79 x 10^5)
(6 x 8.79) x 10^14
52.74 x 10^14

Amount of freshwater available
= 6x10^(9) x 8.79x10^(5)
=10^(14) x 52.74
=5.274 x 10^(15) L

you cannot count because there is always new fresh water generated.
