To solve the rational equation , how can the expression  be rewritten using the least common denominator?a.)b.)c.)d.)

To effectively address the task of rewriting the expression from the rational equation using the least common denominator (LCD), we'll go through the steps below. However, since there's no specific rational equation or expression provided in your question, I'll outline a general approach you can take:

1. Break Down the Problem

   • Identify all the denominators in the rational equation.
   • Determine the least common denominator (LCD) among these fractions.

2. Relevant Concepts

   • The least common denominator (LCD) is the smallest multiple that is common to all denominators. For example, if you have denominators of $2$, $3$, and $4$, the LCD would be $12$.

3. Analysis and Detail

   • Write each denominator in its prime factorized form.
   • The LCD will be found by taking the highest power of each prime that appears across the denominators.
   • Once the LCD is decided, you can rewrite each expression in the equation by multiplying it by a factor that will yield the LCD.

4. Verify and Summarize

   • Check each rewritten expression to ensure they all are over the common denominator.
   • Summarize the findings by presenting each expression rewritten using the LCD.

Final Answer

Once you establish the least common denominator and apply it across the rational expressions, you’ll have successfully rewritten them. If you provide specific expressions, I can assist you in calculating the LCD and rewriting the expressions accordingly.
