Question

Use any method to simplify complex fraction.

Answer 1

\[\left(\begin{matrix}25z^2x^8 \\ 49\end{matrix}\right)/\left(\begin{matrix}175x^4z^7 \\ 21\end{matrix}\right)\]

Answer 2

that easy we been laerned how to do that

Answer 3

I'm not sure on how to do it can you help me out?

Answer 4

\[{25z^2x^8 \over 49} \div {175x^4z^7 \over 21}?\]

Answer 5

Yes that is the problem sorry should have put division sign

Answer 6

sure just do the like terms first like 175x -25x then subtract one from z then substract 49 from 21

Answer 7

\[={25z^2x^8 \over 49}\times {21 \over 175x^4z^7}={25z^2x^8 \over 175x^4z^7}\times{21 \over 49}={x^4 \over 7z^5}\times{3 \over 7}={3x^4 \over 49z^5}.\]

Answer 8

thanks man i really appreciate it.
