Q. Subtract.\newline5y36c2k33c3u38d3k2 \frac{5 y^{3}}{6 c^{2} k^{3}}-\frac{3 c^{3} u^{3}}{8 d^{3} k^{2}}
  1. Identify Terms: Identify the terms to subtract.
  2. Write Down: Write down the terms.\newline5y36c2k33c3u38d3k2\frac{5y^{3}}{6c^{2}k^{3}} - \frac{3c^{3}u^{3}}{8d^{3}k^{2}}
  3. Find Common Denominator: Find a common denominator.\newlineThe least common multiple (LCM) of 6c2k36c^{2}k^{3} and 8d3k28d^{3}k^{2} is 24c3d3k324c^{3}d^{3}k^{3}.
  4. Rewrite Fractions: Rewrite each fraction with the common denominator.5y36c2k3×4d34d33c3u38d3k2×3c3c×kk\frac{5y^{3}}{6c^{2}k^{3}} \times \frac{4d^{3}}{4d^{3}} - \frac{3c^{3}u^{3}}{8d^{3}k^{2}} \times \frac{3c}{3c} \times \frac{k}{k}
  5. Perform Multiplication: Perform the multiplication.\newline20d3y324c2d3k39c4u3k24d3k3\frac{20d^{3}y^{3}}{24c^{2}d^{3}k^{3}} - \frac{9c^{4}u^{3}k}{24d^{3}k^{3}}
  6. Combine Terms: Combine the terms over the common denominator.\newline(20d3y39c4u3k)/(24c3d3k3)(20d^{3}y^{3} - 9c^{4}u^{3}k)/(24c^{3}d^{3}k^{3})
  7. Simplify Expression: Simplify the expression.\newlineOops, made a mistake in the previous step, should have multiplied 3c3c by k3k^{3} not just kk.
