For all positive integers m, (m) = 3m when m is odd and (m) = ½ m when m is even, which of the following is equivalent to (9)*(6)?
(81) (54) (36) (27) (18)
(81) (54) (36) (27) (18)
9 is odd, so (9) = 3x9 = 27sukhman wrote:For all positive integers m, (m) = 3m when m is odd and (m) = ½ m when m is even, which of the following is equivalent to (9)x(6)?
A) (81)
B) (54)
C) (36)
D) (27)
E) (18)
6 is even, so (6) = 6/2 = 3
So, (9) x (6) = 27 x 3 = 81
BE CAREFUL, the answer choices are as follows:
A) (81)
B) (54)
C) (36)
D) (27)
E) (18)
[as opposed to 81, 54, 36, etc]
So, which of the 5 answer choices is equivalent to 81?
Since 27 is odd, (27) = 3 x 27 = 81
So, the correct answer is D
