Homework Statement


(* to the power of) 20m3 equals to
a)2x10-8km3
b)2x10*6cm3
c)2x10*5dm3
d)2x19*9mm3

Homework Equations


ok
1000m=1km
so 1km3 is equal to 1000x1000x1000=10*9
so 10*9/20m3=50,000,000

1km3/50x10*6=20
from here I'm confused
........

The Attempt at a Solution

"1km3/50x10*6=20

Does writing it this way make it any easier?
[tex]\frac{1}{50\times10^{6}} km^3 =
\frac{1}{50}\times
\frac{1}{10^{6}}km^3 = 20m^3[/tex]

What you've done above is correct (other than leaving out the m^3 at the end), i.e.

1000m=1km
so 1km3 is equal to 1000x1000x1000=10*9
so 10*9/20m3=50,000,000

1km3/50x10*6=20

What's 1/50? And how would you write 1/106 as a power of 10?
 

1. What is the purpose of asking someone to check a math question?

Asking someone to check a math question is a common practice in order to ensure accuracy and avoid making mistakes. It allows for a second set of eyes to review the problem and catch any errors that may have been overlooked.

2. How should I phrase my request for someone to check my math question?

It is important to clearly state the specific math question or problem that you would like someone to check. Be sure to provide all necessary information and show your work or steps taken to solve the problem.

3. Who is the best person to ask to check my math question?

The best person to ask to check your math question would be someone who is knowledgeable in the subject and has a good understanding of the concepts being used. This could be a teacher, tutor, or classmate.

4. Is it okay to ask for someone to check my math question multiple times?

There is nothing wrong with asking for someone to check your math question multiple times, as long as you are genuinely seeking to understand and improve your understanding. However, it is important to also try to solve the problem on your own and only ask for help after putting in effort.

5. How can I improve my math skills when asking someone to check my math question?

When asking someone to check your math question, it is important to actively listen to their feedback and understand any mistakes that were made. This will help you improve your skills and avoid making the same mistakes in the future. Additionally, practicing regularly and seeking help when needed can also improve your math skills.
