Hello,

For this problem you have to substitute whatever you value for M is into the equation 3M-odd or 1/2M-even

You was Given 9 as M and 6 as M

So you the formula tells you to substitute those values into the equation to get:

= [9]*3 times [6]*(1/2)

= 27 * 3

= 81

as you can see doing the same thing for [27] gives you 81 also.

I found the correct way to solve this problem. Here is the link in case you want to know why the correct answer is 27

hey anthony!

thanks for posting this question and the solution. unfortunately i still dont get it...... would you (or anyone else) try to explain to me why it is [27]?

i was absolutely certain that the answer should be 36 or [18] ...

thanks,

sven

The correct answer is 27.

The question is asking which of the following is equivalent to (9) x (6)

When (m) is odd, we use the formula (m) = 3m. Therefore 9 is odd and we plug it into the formula. We now have (m) = 3*9 = 27 for the first part of the equation.

The second part of the equation states if we have an even number we use (m) = 1/2(m). We now have (6)*1/2 = 3 for the second part of the equation.

Now we put both numbers into the formula and solve: 27 * 3 = 81. Here is tricky part. 81 is an odd number and the question asks you which of the numbers below is equivalent to (9) x (6).

Since 81 is odd, we need to find what number works with the original formula, m = 3m. Now you need to plug and solve. (81) = 3m. This equals 27 and solves the problem.

It took me a while to figure this problem out too. I hope this explanation helps.
