This program is very useful for filling out tax forms. Although my returns are not complicated, getting the credit that I am due for foreign taxes is too much for tax programs like HR Block and too much for most accountants. I have returned to my old habit of doing my returns manually. This PDFfiller program makes it feasible.

I was nice to fill-out a PDF form in type. Easy to use. Helpful with PDF form filling. Much more professional to submit a form in type to a city administration. It was a bit expensive for a short time need of 1-2 months. We only needed it for submittal of forms to a city administration.

I like having this resource as an option. I like that it offers a clean, crisp look for documents. The forms or finished forms look very neat when they are typed. It seems like a great option for persons to use when their handwriting is not legible. The words do not stay within the lines. I used the software recently and the office manager had to retype the form because the words did not fit.

What do you like best? I work remotely, don't have a staff or colleagues at my finger tips and find myself in constant need of sending out advertising agreements in an efficient manner. I have the ability with PDF filler to quickly revise and add to routine contracts efficiently. What do you dislike? The process, of saving and downloading revisions sometimes requires extra clicks and can be simplified. Recommendations to others considering the product: a good option for a quick fix What problems are you solving with the product? What benefits have you realized? Quick revisions are customization are the greatest benefits for my work

Start with the equation: For example, log x = log (x — 2) + 3. Rearrange the terms: log x — log (x — 2) = 3. Apply the law of logarithms: log (x/x-2) = 3. Raise both sides to a power of 10: x ÷ (x — 2) = 3. Solve for x: x = 3.
Step 1: bring all the logs on the same side of the equation and everything else on the other side. Step 3: Exponential to cancel the log (run the hook). Step 4: Solve for x. Step 5: Check your answer. Step 1: Take logs of both sides using one of the given bases.
