Is it possible for a logarithm to equal a negative number?
Yes. The logarithm of 1 is zero; the logarithm of any number less than one is negative. For example, in base 10, log(0.1) = -1, log(0.01) = -2, log(0.001) = -3, etc.
What is log base 5of 125?
log(5)125 = log(5) 5^(3) = 3log(5) 5 = 3 (1) = 3 Remember for any log base if the coefficient is the same as the base then the answer is '1' Hence log(10)10 = 1 log(a) a = 1 et.seq., You can convert the log base '5' , to log base '10' for ease of the calculator. Log(5)125 = log(10)125/log(10)5 Hence log(5)125 = log(10) 5^(3) / log(10)5 => log(5)125 = 3log(10)5 / log(10)5 Cancel down by 'log(10)5'. Hence log(5)125 = 3 NB one of the factors of 'log' is log(a) a^(n) The index number of 'n' can be moved to be a coefficient of the 'log'. Hence log(a) a^(n) = n*log(a)a Hope that helps!!!!!
Why is there ten digits in the base ten system?
In any system of counting, there are exactly the same number of digits as the base. They go from 0 to one less than the base.
When one factor in a multiplication problem is less than one is the product greater or less than the other one?
When one factor is less than one, the product will be less than the other factor.
Is three fourths and two thirds greater or less than one?
It is less than. You see if its not one whole than its less than one.

How do you use your calculator to evaluate log 25.65?
log 25.65 First of all there are two 'logarithm' functions on a calculator. They are shown by 'log', and 'ln'. 'Log' is the function of logarithms to base '10'. 'ln' is is the function of logarithms to the 'natural base' , which is 'e = 2.7818...;. However, in your question you quote 'log' , so it is assumed you are working to base '10'. On my calculator press ' clear' , then 'log' the enter '25.65' , then 'equals(-)'. The answer is '1.409087369.... ' NB My calculator is a 'Casio fx-83MS' ; a rather 'ancient machine'. Different calculator manufacturers will have a different function rountine. Read the instruction paper with your calculator.
What solid have more than one edge and less than 10 edges?
A pyramid with a triangular base. It has 6 edges, or a pyramid with a square base, which has 7 edges
Why is there ten digits in the base ten system?

How do you input log base 3 in a calculator?
Let y = log3 x⇒ x = 3yTaking logs to any base you like of both sides gives:log x = y log 3⇒ y = log x/log 3So to calculate log base 3 on a calculator, use either the [log] (common or log to base 10) or [ln] (natural or to base e) function key for the log above, that is use one of:[(] [log] [] [÷] [log] [3] [)][(] [ln] [] [÷] [ln] [3] [)][(] [] [log] [÷] [3] [log] [)][(] [] [ln] [÷] [3] [ln] [)]Things in square brackets [] represent keys on the calculator; the is the number of which you want the logarithm to base 3.Use one of 1 & 1 if your calculator is a more modern one that uses natural representation that looks like maths whereby the calculation is done once you've finished entering it all and the numbers for functions follow them.Use one of 3 & 4 if your calculator is an older style one that when you press a function key it acts immediately on the number displayed on the screen.The parentheses (round brackets) are included above so that the whole expression evaluates to log3.
The perimeter of a rectangle is 38mm.the height is one less than three times the base what is the length of the base?
5mm is NOT TRUE You find it by dividing it by 2
Is one quarter more or less than one third?
one quarter is less than one third
The force required to split a log by using a wedge is less if?
The force required to split a log using a wedge is less if the wedge is sharper and has a steeper angle. Additionally, a larger wedge will require less force compared to a smaller one.
When one factor in a multiplication problem is less than one is the product greater or less than the other one?
When one factor is less than one, the product will be less than the other factor.
Is three fourths and two thirds greater or less than one?
It is less than. You see if its not one whole than its less than one.
How do you find logarithms using a calculator?
If you are using a scientific calculator you will have a key labelled "log". To find the logarithm (to base 10) of a number, simply enter "log" followed by the number that you want to log. If you want a natural logarithm - log to the base e - use the "ln" key instead. If you haven't got a scientific calculator, use the one on your computer.
