1 answer

To simplify the expression \(\frac{63}{28z^8}\), we can start by simplifying the numerical part and the variable part separately.

  1. Simplify the numerical part: \[ \frac{63}{28} \] Both 63 and 28 have a common factor. The greatest common divisor (GCD) of 63 and 28 is 7. \[ \frac{63 \div 7}{28 \div 7} = \frac{9}{4} \]

  2. Now include the variable part: \[ \frac{9}{4z^8} \]

Thus, the simplified expression is: \[ \frac{9}{4z^8} \]

This is the final result.
