For example, the fraction 8/10 simplifies to 4/5 by dividing the numerator and denominator by the common factor of 2.\(c^3 \times c^2\). To answer this question, write \(c^3\) and \(c^2\) out in ...

For example, the fraction 8/10 simplifies to 4/5 by dividing the numerator and denominator by the common factor of 2.\(d^4 \div d^5\). Using index laws for division, subtract the powers.
