Question

$25a^5{b}^5{c}^3÷5a^4{b}^4{c}^2$ =

• A. 5
• B. $5abc$
• C. $5ab$
• D. $5bc$

Answer 1

The correct option is B

$5abc$

Given

$25a^5{b}^5{c}^3÷5a^4{b}^4{c}^2$

= $\frac{25a^5{b}^5{c}^3}{5a^4{b}^4{c}^2}$

$\frac{a^n}{a^m}=a^{n-m}$

$\Rightarrow$ $\frac{25}{5}\times a^{5-4}{b}^{5-4}{c}^{3-2}$

= $5abc$
