An equation using the numbers 2,4,6 and 8 to get the answer to be nine. You may use multiplication, division, subtraction, addition, and parenthesis. im so stumped.
Can you use exponents?
If so, how about
(6/2)^(8/4) = 3^2 = 9 ?
If not, try this:
8 + [6/(2+4)] = 9
To create an equation using the numbers 2, 4, 6, and 8 that equals 9, you can try the following steps:
1. Start by considering the simplest arithmetic operations that could result in 9: addition (+) and subtraction (-).
2. As 2 + 4 + 6 + 8 = 20, it is clear that just using addition will not give us the desired result.
3. So, let's try using subtraction:
- Begin with the number 8, as it is the largest in the given set.
- We need to subtract values that result in 9 from 8.
- Notice that subtracting 2 or 4 from 8 will give 6 or 4, respectively, which are less than 9.
- However, if we subtract 6 from 8, we get 2, which when added to the remaining 4, will give us 6.
- Now, we have 6 + 2 = 8.
4. At this point, our equation looks like (8 - 6) + 2 = 8.
- However, this only equals 8, not 9 as desired.
5. We need to use another operation to make the equation equal to 9.
- The only operation left is multiplication (*), as we've already used addition (+), subtraction (-), and the numbers given (2, 4, 6, and 8).
- Let's consider multiplying the existing numbers: 6 * 2 = 12.
6. Now, we can adjust our equation to use multiplication and reach the desired result:
- ((8 - 6) * 2) - 4 = 9.
- In this equation, we first subtract 6 from 8, which gives us 2.
- We then multiply this result by 2 to get 4.
- Finally, we subtract 4 from 4, which equals 9.
Therefore, the equation (8 - 6) * 2 - 4 = 9 is one way to use the given numbers to obtain the desired result.
