Question

Divide a monomial by a monomial.
$50a^2{b}^4÷2a{b}^2$

• A. $25a^2{b}^2$
• B. $50a{b}^2$
• C. $25a{b}^2$
• D. $20a{b}^2$

Answer 1

The correct option is C $25a{b}^2$

$50a^2{b}^4÷2a{b}^2=\frac{50a^2{b}^4}{2a{b}^2}=25\frac{a^2}{a}\times \frac{b^4}{b^2}$

$=25a^{2-1}{b}^{4-2}$

$=25a{b}^2$
