Answer 3

Calculating z⁻⁸·z/z⁻⁴

To solve the expression z⁻⁸·z/z⁻⁴, we can simplify it step by step.

First, let's simplify z⁻⁸·z. Since z⁻⁸ is the same as 1/z⁸, we can rewrite the expression as 1/z⁸·z.

Now, we can simplify this further by using the properties of exponents. When we multiply like bases, we add the exponents. Therefore, 1/z⁸·z can be simplified to 1/z⁷.

So, z⁻⁸·z simplifies to 1/z⁷.

Next, we divide 1/z⁷ by z⁻⁴. When we divide like bases, we subtract the exponents. Therefore, 1/z⁷ ÷ z⁻⁴ can be simplified to 1/z⁷-(-4), which is equivalent to 1/z³.

Therefore, z⁻⁸·z/z⁻⁴ simplifies to 1/z³.

This is the final simplified form of the given expression.
