# Find the value of y. Did I do this problem correct?

• Voltrical
In summary, the conversation is about converting units in a problem and the mistake of raising each side to the wrong power. The correct answer should have units of length^(9/2)*time^(9/2) or m2/s2 in SI units.

## The Attempt at a Solution

What happened to all the units in line 2?

After dividing x by a, you should have gotten rid of the units of mass so your final answer shouldn't have any.

I converted everything to SI units and went on from there, it makes everything easier in my opinion. I'm not sure if I did it right and I probably shouldn't post my answer but I think you should have units of length^(9/2)*time^(9/2) at the end.

I get
length2 * time-2

Did you raise each side to the power 3/2 instead of 2/3?

Yes, you're right, my mistake. Now I'm getting m2/s2 with SI units.

## 1. How do I find the value of y?

To find the value of y, you need to solve the equation or problem that involves y. This may involve using algebraic manipulation, substitution, or other mathematical techniques.

## 2. What if my answer for y does not match the given solution?

If your answer for y does not match the given solution, it is possible that you made a mistake while solving the problem. Double check your work and make sure you followed the correct steps. If you are still unsure, you can ask a teacher or tutor for help.

## 3. How do I know if I did the problem correctly?

If you followed the correct steps and your solution matches the given answer, then you likely did the problem correctly. However, it is always a good idea to check your work and make sure you did not make any errors.

## 4. Can I use a calculator to find the value of y?

It depends on the problem at hand. Some problems may require you to use a calculator, while others may not. It is important to read the instructions and understand what is expected before using a calculator.

## 5. What if I am still unsure about the correct answer for y?

If you are still unsure about the correct answer for y, you can ask for help from a teacher, tutor, or classmate. It is also helpful to review the steps and techniques used to solve the problem to better understand the concept.
