Question

Simplify: x0 y-3 / x2 y-1

Answer 1

$\frac{x {}^{0}y {}^{ - 3} }{x {}^{2}y {}^{ - 1} } \\ = \frac{1y {}^{ - 3} }{ {x}^{2}y {}^{ - 1} } \\ = \frac{1 \times 1}{ {x}^{2} y {}^{2} } \\ \\ = \frac{1}{ {x}^{2}y {}^{2} }$

Step by Step Explanation:

• Evaluate the power: Any non-zero expression raised to the power of 0 equals 1
• Simplify: Simplify the expression
• Calculate the product: Any expression multiplied by 1 remains the same.
