Question

What is the simplified form of the following expression?
  

Answer 1

(4/7)^3=.1865

6xyz/2xz simplifies to 3y

Answer 2

Part a) $(\frac{4}{7} )^{3}$

$(\frac{4}{7} )^{3} =\frac{4^{3}}{7^{3}}= \frac{64}{343}$

therefore

the answer part a) is equal to

$\frac{64}{343}$

Part b) $\frac{6xyz}{2xz}$

$\frac{6xyz}{2xz}= \frac{(2xz)(3y)}{2xz} = 3y$

therefore

the answer Part b) is equal to

$3y$
