Question

State True or False.

Simplify: $x^{10}{y}^6÷x^3{y}^{-2}$, then answer is $x^7{y}^8$.

• A. True
• B. False

Answer 1

The correct option is A True

$\Rightarrow x^{10}{y}^6÷x^3{y}^{-2}\Rightarrow \frac{x^{10}{y}^6}{x^3{y}^{-2}}$
$\because x^m÷x^n=x^{m-n}$
$\Rightarrow x^{10-3}{y}^{6-(-2)}\Rightarrow x^7{y}^8$
