How do you reduce logarithms?
To rid an equation of logarithms, raise both sides to the same exponent as the base of the logarithms. In equations with mixed terms, collect all the logarithms on one side and simplify first.
What are the rules of logarithms?
The rules apply for any logarithm logbx, except that you have to replace any occurence of e with the new base b. The natural log was defined by equations (1) and (2)….Basic rules for logarithms.
| Rule or special case | Formula |
|---|---|
| Quotient | ln(x/y)=ln(x)−ln(y) |
| Log of power | ln(xy)=yln(x) |
| Log of e | ln(e)=1 |
| Log of one | ln(1)=0 |

What is the power rule for logarithms?
When a logarithmic term has an exponent, the logarithm power rule says that we can transfer the exponent to the front of the logarithm. Along with the product rule and the quotient rule, the logarithm power rule can be used for expanding and condensing logarithms.

What is a logarithm in simple terms?
logarithm, the exponent or power to which a base must be raised to yield a given number. For example, 23 = 8; therefore, 3 is the logarithm of 8 to base 2, or 3 = log2 8. In the same fashion, since 102 = 100, then 2 = log10 100.
What is the basic form of the logarithmic function?
The logarithmic function has the basic form of: The logarithm of the multiplication of x and y is the sum of logarithm of x and logarithm of y. The logarithm of the division of x and y is the difference of logarithm of x and logarithm of y. The logarithm of x raised to the power of y is y times the logarithm of x. log b ( x y) = y ∙ log b ( x)
What is the formula to calculate log b?
log b ( x ∙ y) = log b ( x) + log b ( y) Logarithm quotient rule. log b ( x / y) = log b ( x) – log b ( y) Logarithm power rule. log b ( x y) = y ∙ log b ( x) Logarithm base switch rule. log b ( c) = 1 / log c ( b) Logarithm base change rule. log b ( x) = log c ( x) / log c ( b)
How do you find the product of logarithm?
Logarithm product rule. The logarithm of the multiplication of x and y is the sum of logarithm of x and logarithm of y. log b(x ∙ y) = log b(x) + log b(y) For example: log 10(3 ∙ 7) = log 10(3) + log 10(7)
What are the rules of base b logarithm?
Logarithm Rules. The base b logarithm of a number is the exponent that we need to raise the base in order to get the number. Logarithm definition. When b is raised to the power of y is equal x: Then the base b logarithm of x is equal to y:
