So, this is six ‘x’s multiplied together, or x to the 6. Using the index law for division, the calculation simplifies to x to the 4 subtract negative 2. Which again equals x to the 6.

\(d^4 \div d^5\). Using index laws for division, subtract the powers. \(d^4 \div d^5 = d^{4 - 5} = d^{-1}\). This is an example of a negative index. But \(d^4 \div d^5\) also equals \(\frac{d ...
