1000 = 10 ^ 3
8000 = 8 * 10 ^ 3
3.25 * 10 ^ - 22 * 8 * 10 ^ 3 =
3.25 * 8 * 10 ^ - 22 * 10 ^ 3 =
26 * 10 ^ - 22 * 10 ^ 3 =
26 * 10 ^ ( - 22 + 3 ) =
26 * 10 ^ ( - 19 ) =
2.6 * 10 * 10 ^ ( - 19 ) =
2.6 * 10 ^ 1 * 10 ^ ( - 19 ) =
2.6 * 10 ^ ( - 19 + 1 ) =
2.6 * 10 ^ - 18
8000 = 8 * 10 ^ 3
3.25 * 10 ^ - 22 * 8 * 10 ^ 3 =
3.25 * 8 * 10 ^ - 22 * 10 ^ 3 =
26 * 10 ^ - 22 * 10 ^ 3 =
26 * 10 ^ ( - 22 + 3 ) =
26 * 10 ^ ( - 19 ) =
2.6 * 10 * 10 ^ ( - 19 ) =
2.6 * 10 ^ 1 * 10 ^ ( - 19 ) =
2.6 * 10 ^ ( - 19 + 1 ) =
2.6 * 10 ^ - 18
