Simplify logarithmic equations

In summary, a logarithmic equation is an equation that contains a logarithm, which is the inverse of an exponential function and is used to solve equations with exponential terms. To simplify a logarithmic equation, you can use rules such as the power rule, product rule, quotient rule, and change of base rule. The power rule states that the logarithm of a number raised to a power is equal to the product of that power and the logarithm of the number. The product rule states that the logarithm of a product is equal to the sum of the logarithms of the individual factors. The quotient rule states that the logarithm of a quotient is equal to the difference of the logarithms of the individual terms.

-3 is the correct answer.

log2(1/8) = -3
This equation is equivalent to 2-3 = 1/8.

FAQ: Simplify logarithmic equations

What is a logarithmic equation?

A logarithmic equation is an equation that contains a logarithm. A logarithm is the inverse of an exponential function and is used to solve equations with exponential terms.

How do you simplify a logarithmic equation?

To simplify a logarithmic equation, you can use the rules of logarithms to rewrite the equation in a simpler form. These rules include the power rule, product rule, quotient rule, and change of base rule.

What is the power rule for simplifying logarithmic equations?

The power rule states that the logarithm of a number raised to a power is equal to the product of that power and the logarithm of the number. In other words, logb(xn) = nlogb(x).

What is the product rule for simplifying logarithmic equations?

The product rule states that the logarithm of a product is equal to the sum of the logarithms of the individual factors. In other words, logb(xy) = logb(x) + logb(y).

What is the quotient rule for simplifying logarithmic equations?

The quotient rule states that the logarithm of a quotient is equal to the difference of the logarithms of the individual terms. In other words, logb(x/y) = logb(x) - logb(y).
