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,

$25a^5{b}^5{c}^3÷5a^4{b}^4{c}^2$

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

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

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

$=5abc$
