Wonderful - the only way to make it better is to make it free or at least cut the cost in half. Thanks so much!! All in all a wonderful service and really worth the price!

It was just what i was looking for...im not very computer literate but WAS NOT hard to learn. I do think a few features could be added or made easier. I WAS NOT HAPPY WITH THE COST. Its mighty ridiculous! For the amount of money i spent and the length of time... S***, unless you are in the business of "screw ups" "uh-oh"ers, the presidents Secretary for his twitter account...or a lawyer. I don't think you get enough time for the cost. And VERY UNSATISFIED with the small print that is located UNDER the nice AFFORDABLE FAKE SALE PRICE at the beginning of the website

Pratical and
PDFfiller is a good option whenever you need to fill forms or edit a pdf file. The online version is also an advantage.
If you don't use it a lot, the princing will be a little excessive to pay every month. A "pay as you go" or pay as you use.

My experience with PDFiller was fantastic. I was amazed how easy to use!
I already answered this question.
Ability to locate forms and fill out online to produce a very professional looking and very neat document. This product was a winner for me. Save me a lot of time.

New User but Impressed
Just now starting to use, but am thoroughly impressed. I'm sure as I get used to the software it will increase to 5 stars!

PdfFiller is great!
Very easy to use to do any type of form. The only thing that sucks is the price because I don't use it that much to pay $96 for it annually. If it was $40 or less I'd be all in. Great app to get any job done whether it's personal or business. Thank you.

pdfFiller were able to address a problem I had with excellent and speedy support. The Support Team provided an experience, which was truly professional, understanding and considerate to my needs.
2020-12-23
I would love to attend a webinar eventually, but time right now does not allow it. I have been extremely pleased with pdfFiller and recommend it to everyone I know who has to fill out a lot of forms.
Maybe slower than hand writing , but legible which is extremely important. My biggest issue is somehow I have two accounts with other documents saved and do not know how to merge them. That was my problem not realizing i had an account already. Thank yall so much!!!

How do you find the sum of a log?
A useful property of logarithms states that the logarithm of a product of two quantities is the sum of the logarithms of the two factors. In symbols, logo(XY)=logo(x)+logo(y). (x y) = log b (x) + log b
What is the log formula?
When we take the logarithm of both sides of ELN(XY)=ELN(x)+LN(y), we obtain LN(ELN(XY))=LN(ELN(x)+LN(y)). The logarithms and exponential cancel each other out (equation (4)), giving our product rule for logarithms, LN(XY)=LN(x)+LN(y).
Can you distribute a log?
Can you distribute log on log(x+y)? X + y = XY, In general, no. The logarithm of a sum is as simplified as it gets, unless the sum itself can in some way be simplified.
Can you distribute natural log?
Rule one: if LN(a) = LN(b), then a must equal b. Rule two: LN(ab) = LN(a) + LN(b) for all positive real numbers. Therefore, LN does not distribute over its argument.
What happens when you divide logs?
Division. The rule when you divide two values with the same base is to subtract the exponents. Therefore, the rule for division is to subtract the logarithms. The log of a quotient is the difference of the logs.
How do you get rid of a log?
A logarithm is the inverse of an exponent. The equation log x = 100 is another way of writing 10x = 100. This relationship makes it possible to remove logarithms from an equation by raising both sides to the same exponent as the base of the logarithm.
