Question

Add
5 1
____ + ____
4z^3 10z^2

Answer 1

\[\large \frac{5}{4z^3}+\frac{1}{10z^2}\]


\[\large \frac{5*5}{5*4z^3}+\frac{1}{10z^2}\]


\[\large \frac{25}{20z^3}+\frac{1}{10z^2}\]


\[\large \frac{25}{20z^3}+\frac{2z*1}{2z*10z^2}\]


\[\large \frac{25}{20z^3}+\frac{2z}{20z^3}\]


\[\large \frac{25+2z}{20z^3}\]
So \[\large \frac{5}{4z^3}+\frac{1}{10z^2}=\frac{25+2z}{20z^3}\]
