642 x 3 = 1926
77,040 because 107 x 2 = 214 214 x 3 = 642 642 x 4 = 2568 2568 x 5 = 12840 12840 x 6 = 77040
1.3 x 1019
150,000,000,000,000,000,000 or 15 x 1019
19, of course. Review your logarithmic rules.
642 x 3 = 1926
The prime factorization of 642 is 2 x 3 x 107.
1 x 642, 2 x 321, 3 x 214, 6 x 107.
77,040 because 107 x 2 = 214 214 x 3 = 642 642 x 4 = 2568 2568 x 5 = 12840 12840 x 6 = 77040
One electron has - 1.602 X 10 -19 coulomb of charge. So disregarding the negative sign....., 2.86 C/1.602 X 10 -19 C = 1.79 X 1019 electrons in that much charge. ============================
X-rays has a frequency ranging from 3 x 1019 to 1 x 1016 Hertz
use this strategy: integral of (b^x) dx = (b^x)/ln(b) + K [K is integration constant, b is not a variable]rewrite (1/c)^(1-x) = ((1/c)^1)*((1/c)^(-x)) = (1/c)*(c^x). (1/c) is a constant, so bring outside the integral, then let b = c in the formula above, and you have (1/c)*(c^x)/ln(c) + K
X-rays has a frequency ranging from 3 x 1019 to 1 x 1016 Hertz
a negative charge of - 1.6019 x 1019 coulombs
1.3 x 1019
The next number is 77040. Solution: 107 x 2 = 214x 3 = 642 x 4 = 2568 x 5 = 12840 x 6 = 77040
4.8 x 1019 = 48000000000000000000
