Question

How can I solve this? and can you please tell me how step by step.

Answer 1

`((27)/(343))`

Explanation:

This is what you start off with
`((3)/(7))^(3)`

`((3)/(7))^(3)` is also equal to
`((3)/(7))((3)/(7))}((3)/(7))` because the original equation is
`((3)/(7))` multiplied by itself 3 times.

`((3)/(7))((3)/(7))}((3)/(7))`

Multiply the first two fractions straight across

`((9)/(49))((3)/(7))`

Multiply the answer of multiplying the two fractions by
`((3)/(7))`

`((27)/(343))`

Answer 2

Answer:27/343 or 0.0787172

Explanation:

First you need to place the exponent on both the numerator and the demonimator to make 3 to the power of 3 over 7 to the power of 3

Next you evaluate the numerator so 3 to the power of 3 is 27

and 7 to the power of 3 is 343 so your answer in fraction form is 27/343

you can also change into a decimal if you divide the fraction if you need to

Hope this helps
