Question

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

Answer 1

Answer:27/343 or 0.0787172

Step-by-step 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

Answer 2

Answer:

$(\frac{27}{343})$

Step-by-step explanation:

This is what you start off with $(\frac{3}{7})^{3}$

$(\frac{3}{7})^{3}$ is also equal to $(\frac{3}{7})(\frac{3}{7})}(\frac{3}{7})$ because the original equation is $(\frac{3}{7})$ multiplied by itself 3 times.

$(\frac{3}{7})(\frac{3}{7})}(\frac{3}{7})$

Multiply the first two fractions straight across

$(\frac{9}{49})(\frac{3}{7})$

Multiply the answer of multiplying the two fractions by $(\frac{3}{7})$

$(\frac{27}{343})$
