Question

add and simplify if possible
2/9z^3 + 1/6z^2

Answer 1

\[\Large \frac{2}{9z^3} + \frac{1}{6z^2}\]



\[\Large \frac{2*2}{2*9z^3} + \frac{1}{6z^2}\]



\[\Large \frac{4}{18z^3} + \frac{1}{6z^2}\]



\[\Large \frac{4}{18z^3} + \frac{3z*1}{3z*6z^2}\]



\[\Large \frac{4}{18z^3} + \frac{3z}{18z^3}\]



\[\Large \frac{4+3z}{18z^3}\]



So \[\Large \frac{2}{9z^3} + \frac{1}{6z^2}=\frac{4+3z}{18z^3}\]
