5 to the tenth power would be 5 X 5 X 5 X 5 X 5 X 5 X 5 X 5 X 5 X 5, or 9,765,625.
5x5x5x5x5x5=15,625.
(x-5) is the same as x-5
1 x 5 = 5 2 x 5 = 10 3 x 5 = 15 4 x 5 = 20 5 x 5 = 25 6 x 5 = 30 7 x 5 = 35 8 x 5 = 40 9 x 5 = 45 10 x 5 = 50 11 x 5 = 55 12 x 5 = 60 13 x 5 = 65 14 x 5 = 70 15 x 5 = 75 16 x 5 = 80 17 x 5 = 85 18 x 5 = 90 19 x 5 = 95 20 x 5 = 100 and so on... just +5 lol!
625 = 5^4 Why? Let do it step by step:625 = 5 x 125625 = 5 x 5 x 25625 = 5 x 5 x 5 x 55 x 5 x 5 x 5 = 625
5 x 5 x 5 x 5 x 5 x 5 x 5 x 5 = 78,125
5 to the tenth power would be 5 X 5 X 5 X 5 X 5 X 5 X 5 X 5 X 5 X 5, or 9,765,625.
5 x 5 x 5 x 5 x 5 = 3,125
5x5x5x5x5x5=15,625.
(x-5) is the same as x-5
The twelve is an exponent and the five is the base. All you do is 5 x 5 x 5 x 5 x 5 x 5 x 5 x 5 x 5 x 5 x 5 x 5 or five multiplied by itself 12 times.
(x^2 - 25)/(x + 5) = [(x - 5)(x + 5)]/(x + 5) = x - 5
Prime factors are 2, 2, 2, 2, 5, 5, 5, 7 Other factors are combinations, i.e. 2 x 2 = 4 2 x 5 = 10 2 x 7 = 14 5 x 5 = 25 5 x 7 = 35 2 x 2 x 2 = 8 2 x 2 x 5 = 20 2 x 2 x 7 = 28 2 x 5 x 5 = 50 2 x 5 x 7 = 70 5 x 5 x 5 = 125 5 x 5 x 7 = 175 2 x 2 x 2 x 2 = 16 2 x 2 x 2 x 5 = 40 2 x 2 x 2 x 7 = 56 2 x 2 x 5 x 5 = 100 2 x 2 x 5 x 7 = 140 2 x 5 x 5 x 5 = 250 2 x 5 x 5 x 7 = 350 5 x 5 x 5 x 7 = 875 2 x 2 x 2 x 2 x 5 = 80 2 x 2 x 2 x 2 x 7 = 112 2 x 2 x 2 x 5 x 5 = 200 2 x 2 x 2 x 5 x 7 = 280 2 x 2 x 5 x 5 x 5 = 500 2 x 2 x 5 x 5 x 7 = 700 2 x 5 x 5 x 5 x 7 = 1,750 2 x 2 x 2 x 2 x 5 x 5 = 400 2 x 2 x 2 x 2 x 5 x 7 = 560 2 x 2 x 2 x 5 x 5 x 5 = 1,000 2 x 2 x 2 x 5 x 5 x 7 = 1,400 2 x 2 x 5 x 5 x 5 x 7 = 3,500 2 x 2 x 2 x 2 x 5 x 5 x 5 = 2,000 2 x 2 x 2 x 2 x 5 x 5 x 7 = 2,800 2 x 2 x 2 x 5 x 5 x 5 x 7 = 7,000
1,000,000,000 = 109 = (2 x 5)9 = 29 x 59 = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5 x 5 x 5 x 5 x 5 x 5 x 5 x 5 x 5 The factors of one billion are 2 and 5
To find the factors of a number, start with its prime factors. In the case of 2000, these are 2 x 2 x 2 x 2 x 5 x 5 x 5. Multiplying different combinations of these gives us the whole list of factors: 1 22 x 2 = 42 x 2 x 2 = 82 x 2 x 2 x 2 = 1655 x 5 = 255 x 5 x 5 = 1252 x 5 =102 x 5 x 5 = 502 x 5 x 5 = 2502 x 2 x 5 = 202 x 2 x 5 x 5 = 1002 x 2 x 5 x 5 x 5 = 5002 x 2 x 2 x 5 = 402 x 2 x 2 x 5 x 5 = 2002 x 2 x 2 x 5 x 5 x 5 = 10002 x 2 x 2 x 2 x 5 = 802 x 2 x 2 x 2 x 5 x 5 = 400[2 x 2 x 2 x 2 x 5 x 5 x 5 = 2000] So you're quite right, 2000 does have 20 factors.
