## Do you know the base of a common log?

A common logarithm is any logarithm with base 10. Recall that our number system is base 10; there are ten digits from 0-9, and place value is determined by groups of ten. You can remember a “common logarithm,” then, as any logarithm whose base is our “common” base, 10….

What is exponential notation in math?

INTRODUCTION. Exponential notation is a method of simplifying the writing and handling of very large or very small numbers. In exponential notation, a number usually is expressed as a coefficient between one and ten times an integral power of ten, the exponent.

### What is the equation for a logarithmic function?

The logarithmic function, y=logbx, can be shifted k units vertically and h units horizontally with the equation y=logb(x+h)+k.

When do you need to use a logarithmic form?

Logarithmic form is useful when you want to solve for a variable in an exponent. In this lesson, you will learn how to change from exponential to logarithmic form. Sometimes you may have an exponential equation – an equation with a variable in an exponent – and you want to solve for that variable.

Can a logarithmic equation be solved in exponential form?

If the equation is in log form, however, the part inside the ‘log’ is locked up. It can’t be isolated without switching back to exponential form. In equation (1), for example, the y can be easily solved for by subtracting both sides by 5 and then dividing by 3. The y part is ‘free.’
