Question

Divide $25xyzby5z$

Answer 1

Division of monomials.

Quotient of two monomials $=$ (Quotient of their numerical coefficients) (Quotient of their literal coefficients)

$\begin{array}{rcl}25xyzby5z& =& \frac{25\times x\times y\times z}{5\times z}\\ & =& 5\times x\times y\\ & =& 5xy\end{array}$

Therefore, the result of divison is $5xy$.
