Write the equation in logarithmic form

How do you write an equation in logarithmic form?

To change from exponential form to logarithmic form, identify the base of the exponential equation and move the base to the other side of the equal sign and add the word “log”. Do not move anything but the base, the other numbers or variables will not change sides.

How do you write an equation in equivalent logarithmic form?

Every equation that is in exponential form has an equivalent logarithmic form, and vice versa. Both equations have a ‘b,’ the base, an x, and a y. These two equations are equivalent, just like these two equations are equivalent: y = x + 9 and y – 9 = x. Using algebra, you can get from one to the other.

How do you convert a logarithmic equation to exponential form?

How To: Given an equation in logarithmic form logb(x)=y l o g b ( x ) = y , convert it to exponential form. Examine the equation y=logbx y = l o g b x and identify b, y, and x. Rewrite logbx=y l o g b x = y as by=x b y = x .

What are the logarithm rules?

Basic rules for logarithms

Rule or special caseFormula
Productln(xy)=ln(x)+ln(y)
Quotientln(x/y)=ln(x)−ln(y)
Log of powerln(xy)=yln(x)
Log of eln(e)=1

What is the base of a common log?

In mathematics, the common logarithm is the logarithm with base 10. It is also known as the decadic logarithm and as the decimal logarithm, named after its base, or Briggsian logarithm, after Henry Briggs, an English mathematician who pioneered its use, as well as standard logarithm.

What is exponential form?

exponential form. • a way of representing repeated multiplications of the same number. by writing the number as a base with the number of repeats. written as a small number to its upper right.

How do you write scientific notation?

The proper format for scientific notation is a x 10^b where a is a number or decimal number such that the absolute value of a is greater than or equal to one and less than ten or, 1 ≤ |a| < 10. b is the power of 10 required so that the scientific notation is mathematically equivalent to the original number.

What’s a standard form?

Standard form is a way of writing down very large or very small numbers easily. So 4000 can be written as 4 × 10³ . This idea can be used to write even larger numbers down easily in standard form. Small numbers can also be written in standard form.

Factoring an equation

How do you factor algebraic equations? So, if, in your equation, your b value is twice the square root of your c value, your equation can be factored to (x + (sqrt(c)))2. For example, the equation x2 + 6x + 9 fits this form. 32 is 9 and 3 × 2 is 6. So, we […]

The equation of exchange can be stated as

What is the equation of exchange equal to? So the equation of exchange says that the total amount of money that changes hands in the economy will always equal the total money value of the goods and services that change hands in the economy. So now the equation of exchange says that total nominal expenditures […]
