.63 is also 63% or 63/100. (432 x .63) is the same as (63% of 432) which is the same as (432 x 63/100).
[H+] = 1 x 10-10 M then pH = 10
- log(1 X 10^-5 M) = 5 14 - 5 = 9 pH ----------
-log(2.3 X 10^-3 M) = 2.6 14 - 2.6 = 11.4 pH ( OH - )

104m (meters) is 113.736 yards.meters x 1.09361 = yards
4.25*104m
63 x 63 = 3969
The first ten positive integer multiples of 63 are as follows: 1 x 63 = 63 2 x 63 = 126 3 x 63 = 189 4 x 63 = 252 5 x 63 = 315 6 x 63 = 378 7 x 63 = 441 8 x 63 = 504 9 x 63 = 567 10 x 63 = 630
38,000m = 3.8 × 104m
5.5 × 104m or 5.5E4m
There are 3 factor pairs of 63: 63 = 1 x 63 63 = 3 x 21 63 = 7 x 9
Sticking to integers: 7 x 9 = 63 3 x 21 = 63 1 x 63 = 63
1 x 63 is 63 2 x 63 is 126 ....
1 x 63, 3 x 21, 7 x 9, 9 x 7, 21 x 3, 63 x 1.
Make common units first, such as meters. 100km = 105m 10km = 104m 0.5mm = 5*10-4m Answer is 5*105m3 = 500,000 cubic meters
38000m = 3.8 × 104m
