What is the value of 2 * log 5 + log 8 - (1/2) * log 4 = ? Assumed all Logs are of base 10
2
2 * log 5 + log 8 - (1/2) * log 4 =log 25 + log 8 - log 2 = log25*8/2 = log100 = 2
If the following is true, can you find the value of (4 + 9)?
7 + 7 = 2 8 + 8 = 4 8 + 5 = 1 6 + 9 = 3 10 + 11 = 9
Calculate the number of ordered triples (A1, A2, A3) such that:
A1 ∪ A2 ∪ A3 = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} A1 ∩ A2 ∩ A3 = ∅
Write your answer as 2a3b5c7d where a, b, c, d are non-negative integers.
If possible fill + or - for o and make this true, if not possible then provide the reasoning...
1 o 1/2 o 1/3 o 1/4 o 1/5 o 1/6 o 1/7 o 1/8 o 1/9 o 1/10 o 1/11 o 1/12 = 0
If log 2 + log (3x + 1) = log (2x - 9) + 2, then what is the value of x? Note : Assume all log represented above is to the base of 10.
