Example Question - subtraction of exponents

Simplifying Exponential Expressions

The expression in the image shows \(z^8\) multiplied by \(\frac{1}{z^7}\). To simplify this expression, you can use the property of exponents that states when dividing like bases, you subtract the exponents: \(z^8 \cdot \frac{1}{z^7} = \frac{z^8}{z^7} = z^{8-7} = z^1 = z\) So the simplified form of the expression is \(z\).
