3 x 3 x 3 x 7 x 7 = 1323The factors of 1323 are 1, 3, 7, 9, 21, 27, 49, 63, 147, 189, 441, 1323
This isn't a great example, because the powers (exponents) of these two numbers are equal. 22 x 5 = 20 22 x 7 = 28 The GCF is 22 which is 4.
105 times the factor that seems to have been missed out before "... and 7". And all multiples of the result.
Ex: 3/a + 4/b = 7, LCD is ab ab x (3/a) + ab x (4/b) = ab x 7 3b + 4a = 7ab so that the denominators have cancelled. a and b can represent binomials, monomials, polynomials, etc. EX: 3/(x+2) + 4/(x-5) = 7 multiply by ab = (x+2)(x-5)
The prime factorization of 1512 is 2^3 * 3^3 * 7. This means that 1512 can be expressed as the product of these prime numbers raised to their respective powers. The prime factorization helps us understand the unique combination of prime numbers that make up the original number.
28 = 2 x 2 x 7 = 22 x 7
23 x 32 x 7 = 504
x means what ever the missing number is. if it was x over 7, you would have to solve for x.
720 = (7 x 102) + (2 x 101) + (0 x 100)
3 x 3 x 3 x 7 x 7 = 1323The factors of 1323 are 1, 3, 7, 9, 21, 27, 49, 63, 147, 189, 441, 1323
70 = (7 x 101) + (0 x 100)
In countries that use the long scale (based on powers of a million) like Europe700 billionths = 700 x 10-12 = 7 x 10-10In countries that use the short scale (based on powers of a thousand) like USA700 billionths = 700 x 10-9 = 7 x 10-7
The prime factors of 42 are 2 x 3 x 7 and the prime factors of 56 are 23 x 7.The LCM of 42 and 56 is the product of the highest powers of each prime factor,23 x 3 x 7 = 8 x 3 x 7 = 168.
587 = (5 x 102) + (8 x 101) + (7 x 100)
4,702 = (4 x 103) + (7 x 102) + (0 x 101) + (2 x 100)
2,700 = (2 x 103) + (7 x 102) + (0 x 101) + (0 x 100)
what exponential function is the average rate of change for the interval from x = 7 to x = 8.
