– WE WANT TO EVALUATE EACH LOGARITHM ON A CALCULATOR. THEN WRITE A EXPONENTIAL EQUATION TO SHOW THE MEANING OF THE VALUE. NOTICE IN BOTH OF THESE LOGARITHMS THE BASE IS NOT GIVEN THEREFORE WE KNOW IT’S A COMMON LOGARITHM OR LOG BASE 10. MOST CALCULATORS ONLY CONTAIN TWO LOG BUTTONS, LOG FOR COMMON LOG […]

## Ex: Evaluate Natural Logarithms on the Calculator

– WE WANT TO EVALUATE THE GIVEN LOGARITHMS, AND THEN WRITE AN EXPONENTIAL EQUATION TO SHOW THE MEANING OF THE VALUE. NOTICE BOTH OF THESE ARE NATURAL LOGARITHMS, WHICH MEANS BOTH OF THESE ARE LOG BASE E. AND JUST TO REMIND US OF THIS, LET’S GO AHEAD AND PUT THE LITTLE E HERE AND HERE. […]

## Any Base Logarithms on the TI 84 Plus CE Graphing Calculator

Hi this is Rob. I am going to show you how to calculate Logarithms on the TI-84 Plus CE Graphing Calculator. A quick review on logarithms. A logarithm is a way to solve for x, when x is an exponent. For example, 10 to the x power equals 1000. This 10 is called the base. […]

## Evaluating Basic Logarithms Without a Calculator

OK, for these type of problems, what I’m going to do is I’m going to show you a little bit of using these kind of helpful tips with logarithms. These are little healthful properties of logarithms, and they’re going to help me solve these logarithms, or at least evaluate these logarithms, I should say. But […]

## Ex 1: Evaluate Logarithms Without a Calculator – Whole Numbers

– WE WANT TO EVALUATE THE TWO GIVEN LOGARITHMS WITHOUT THE USE OF A CALCULATOR. WE HAVE LOG BASE 3 OF 81 AND LOG BASE 2 OF 32. TO EVALUATE THESE WE’RE GOING TO SET THEM EQUAL TO A VARIABLE, LET’S SAY X, THEN WE’LL WRITE THIS AS AN EXPONENTIAL EQUATION TO DETERMINE THE VALUE […]

## How to Find Log on a Sharp EL-510RN Calculator

Hello and welcome to HP Calcs! My name is Rick and today we will be looking at how to find the log of a number on the Sharp EL-510 RN calculator. The standard setting for logs on our calculator is log base 10. In order to find the log of a number we will use […]

## Ex: Evaluate Logarithmic Expressions without a Calculator – Common Log

We want to evaluate the given log expressions. Notice how for each log the base is not given, so we know these are common logs, meaning each log is base 10. To help us evaluate these log expressions, we’ll form a log equation by setting the expression equal to x, then we’ll write the log […]

Hello guys, let us see today how to calculate logarithms using commercial calculators In this example, let us calculate log six To calculate the log of any number the following steps has tobe followed first type the number you want to take in this example 6 Next press the square root button for 15 times […]

## Master Evaluating a logarithm without a calculator

Welcome ladies and gentlemen. And what I’d like to do is show you how to evaluate logarithms without using a calculator. Now, obviously for a majority of these– or actually for all of these, you could type them into your calculator using the change of base formula unless your calculator can do different bases. But […]
