Use any method to simplify complex fraction.
\[\left(\begin{matrix}25z^2x^8 \\ 49\end{matrix}\right)/\left(\begin{matrix}175x^4z^7 \\ 21\end{matrix}\right)\]
that easy we been laerned how to do that
I'm not sure on how to do it can you help me out?
\[{25z^2x^8 \over 49} \div {175x^4z^7 \over 21}?\]
Yes that is the problem sorry should have put division sign
sure just do the like terms first like 175x -25x then subtract one from z then substract 49 from 21
\[={25z^2x^8 \over 49}\times {21 \over 175x^4z^7}={25z^2x^8 \over 175x^4z^7}\times{21 \over 49}={x^4 \over 7z^5}\times{3 \over 7}={3x^4 \over 49z^5}.\]
thanks man i really appreciate it.
