(\sqrt[5]{x^{7}})^{3}=(x^{\frac{7}{5}})^{3}=x^{\frac{7\cdot3}{5}}=x^{\frac{21}{5}}

Whitepunk [10]

Answer: The greatest number of rows Li Na can plant is 9.


Step-by-step explanation:

Given: Li Na is going to plant 63 tomato plants and 81 rhubarb plants.

Li Na would like to plant the plants in rows where each row has the same number of tomato plants and each row has the same number of rhubarb plants.

To find the greatest number of rows Li Na can plant, we need to find the GCF of 63 and 81.

Since , 63=7\times9\ and\ 81=8\times9

Clearly, GCF(63,81)=9

Therefore, the greatest number of rows Li Na can plant is 9.

Radio waves travel at the speed of light, approximately 300,000,000 m/s. Part A How much time does it take for a radio message t
jenyasd209 [6]

Answer:

Step-by-step explanation:

First you want to understand that every time a radio wave goes 300,000,000 meters a second passes, literally what meter per second means.    of course it doesn't go that far, it goes 384,000 one way and then the same distance back, which makes 768,000.  Under a third of the distance to make 1 second, so it will be less than one second.  

You also want to understand the formula for speed.  speed = distance / time.  Whch also means, to find time you can change it to be time = distance / speed.  And hey, we have distance and speed.  768,000 / 300,000,000 = .00256, I'll leave the significant figures to you unless you need help with them.  but that's .00256 of a second.  or .00256 s
