Prime factors of 8 are 23 Prime factors of 10 are 2 x 5 The LCM is the product of all the primes to their greatest power, so the LCM of 8 and 10 is 23 x 5 = 8 x 5 = 40
8.45 x 10^23 = 845,000,000,000,000,000,000,000
360. 18 = 2 x 32 8 = 23 10 = 2 x 5 lcm = 23 x 32 x 5 = 360
8 x 10-11 = 0.00000000008
20+23 = 9 because anything to the power of 0 is 1, so 1 + (23) and 23 = 8 because 2 x 2 x 2 is 8, and 1+ 8 = 9.
280. 8 = 23 10 = 2 x 5 14 = 2 x 7 lcd = 23 x 5 x 7 = 280
first: 2 7/8 = (8+8+7)/8 = 23/8 next: 23/8 x 4/5 = 23/2 x 1/5 = 23/10 answer: 2 3/10

'10^8' is the easiest way to write it using a computer. Writing '10^8' by hand you would write the '10' and then the '8' at the top right of the '0' but write the '8' smaller. Or... 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 = 10^8
8^2,015 = 5.3250512113293513102752782422973616194431766955007 x 10^1819
It is: 3*10^-8 is equivalent to 0.00000003
