Best Answer

On older calculators you would first have to calculate the log (press the log key), then press the square root key. More recent calculators usually allow you to do the input in the natural order, for example (if your number is 100), sqrt(log(100)).

log of the square root of 'y' = 1/2 sqrt(y)

There are a number of ways. The simplest would be to use a calculator (you probably would not know how to use log tables or a slide rule!) You could find a square root graphically; use numerical methods such as the Newton-Raphson method (not very fast but simple). There is also a method similar to long division, but that is rather complicated.

I can use various methods:Using the square root button [√] on one of my electronic calculators (entering 14 as the number - before or after the [√] button depending upon which calculator it is I'm using)Looking up 14 on the D or C scale of my slide rule and reading the square root off the A or B scale (respectively)Looking it up in Square root tablesFinding the log of 14 (using calculator/slide rule/tables), dividing it by two and then finding the anti-log of the result.A kind of long division as previously explained in other answers - search the web for: calculate square root by handGuess the square root of 14. Divide 14 by the guess. Add the result and the guess together and divide by 2 to give the new guess. Repeat with the new guess until the new guess is approximately the same as the old guess.

Here are four ways: (1). Take the log of 7. (You have to either look it up in a book, find it on a slide rule or calculator, or remember the infinite series definition of the log function and calculate the first 10 or 15 terms of the series.) Then take one third of the log. Then find the anti-log of the quotient. (2). There is a direct procedure to calculate the cube root of a number with a pencil and paper. Although I was working as a professional engineer before calculators and computers were generally available, I learned the pencil method for square roots, but not the one for cube roots. (3). Find the approximate cube root directly on a slide rule. (4). Use a hand-calculator, or a calculator simulator on a computer. These days, it's the only way that makes sense.

x7 = 12 if it was x2 we would square root each side. with x7 we need to fing the seventh root. using a calculator type seven then press the button like a square root but with a small x before it the press 12 to find x Alternative method: Take log 12, divide by 7 then take antilog.

Depends on your calculator. If you have "raise to the power" then use "raise to the power 1/3". If not, try logs: either logs to base 10 or logs to base e will do: find the log, divide it by 3, then find the antilog. For base e, (log sometimes written "ln" meaning "natural log") the antilog is just the exponential : " ex ".

The calculator won't do it.On the calculator, the button marked 10x gives youthe inverse log of the number in the window.

You can use logrithms.Take your log table.Look for the log value of 2.Now divide that value by 2(you should devide by 2 if you want square root,devide by 3 if you want cubic root).Now take the antilog value.It is equal to square root.

The simplest of all, of course, is to use a calculator. All scientific and many basic calculators have the square root function built in. If the number is a perfect square then you can find the square root by "reverse engineering". If 6*6 = 36 then the square root of 36 is 6 (or -6). This will only work for perfect squares (or ratios of perfect squares, such as 4/9), and not for other numbers. Alternatives to the above two are more complicated. There is a method which is a bit like long division but you have to adjust the divisor at each step. It is, unfortunately, too complicated (for me) to explain here. You can use numerical methods (eg Newton-Raphson) to make an estimate and then improve on it. You can also use logarithms if you can lay your hands on logarithm tables. If you want to find the square root of x, find log(x), divide that number by 2 and then look up the antilog of the answer. Easy if you have log tables; impossible if you don't.

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.

log 1.630 = 0.2122 I just put 1.63 into a calculator, pressed Log, and read the answer to four significant places.

To find anti log of a number enter the number as the exponent of 10.
