  • 😑 The product rule for logarithms is used to simplify expressions by converting addition into multiplication.
  • 🍉 Numbers in front of logarithmic terms can be transformed into exponents.
  • 😑 The rules of exponents are applied to simplify the expression further.

Transcript

hello in this problem we have two logarithms and the question is to write it as a single logarithm whose coefficient is one so the idea is to use something called the product rule the product rule says if you have the log base b of x plus the log base b of y that this is equal to the log base b of x times y so the addition turns into multiplication...

Questions & Answers

Q: How does the product rule help simplify logarithmic expressions?

The product rule states that the addition of two logarithms can be converted into the logarithm of their product. By using this rule, we can simplify complex expressions into a single logarithm.

Q: How can we handle numbers in front of logarithmic terms?

Numbers in front of logarithmic terms can be converted into exponents of the log base. This allows us to simplify the expression further by applying the rules of exponents.

Q: What is the rule for combining logarithmic terms with exponents?

When combining logarithmic terms with exponents, we need to multiply the exponents. For example, if we have m^2 raised to the power of -2/3, it becomes m^(-4/3).

Q: How can logarithms with coefficients of one be obtained?

By using the product rule, we can combine logarithmic terms into a single logarithm. The resulting logarithm will have a coefficient of one.

Summary & Key Takeaways

  • The video explains the product rule for logarithms, which states that the sum of two logarithms can be written as the logarithm of their product.

  • To simplify logarithmic expressions with numbers in front, the numbers can be converted into exponents of the log base.

  • The expression is then simplified further by applying the rules of exponents and combining like terms.

  • Finally, the product rule is used to combine the logarithmic terms into a single logarithm with a coefficient of one.
