No, they are opposites, just like multiplication and division are opposites.
The simplest way to do it is to use Logarithms, from a book of Logarithmic Tables and Anti-logarithms. You simply look up the Logarithm of your quantity, then divide that quantity by 2 , and then look up its Anti-logarithm. that will give you the answer.

Logarithms turn multiplication into addition, which is much faster. The same applies for division, except that the logs are subtracted. Using logarithms, finding roots or powers is easy. For example, the square root of a number can be found using 1/2 times the logarithm (plus one more step). Finding square roots is something that happens often in algebra. If you did not have a calculator, square roots would be hard without logarithms.

Michael Stifel published his discovery of logarithms in 1544. John Napier publicly propounded the method of logarithms in 1614. For more details see related link.

Exponents and Logarithms work well together because they "undo" each other (so long as the base "a" is the same).
The base of common logarithms is ten.

Logarithms were invented by John Napier who was a mathematician. He invented other things too, so there was no reason why he couldn't invent the logarithms. Logarithms were invented so people could take short cuts to multiplications! :)

Electrical engineers use logarithms to work on signal Decay.
John Napier of Merchiston. A Scotsman developed logarithms. He published his work in 1614. NB Modern calculators have logarithmic tables integrated into them. However, to multiply say . 45 X 2.67. It can be done by Long Multiplication. However, using 'log tables', it becomes an addition. Hence log 123.45 = 2.09149 log 2.67 = 0.42651 Add the logs. 2.09149 + 0.42651 = 2.518 Anti log ( 2.518) = 329.60971 This compares favourably with direct multiplication at 329.6115 You can use logs for division too!!! Except that you subtract the log values. NB The is a book of Log. Tables. ; 'Castle's Four Figure Tables'. You can also change the log. bases using the formula log(a) b = log(c)b / log(c)a. , where the base is changed from 'a' to 'c' ; '10' to 'e' on a calculator.
You can calculate that on any scientific calculator - like the calculator on Windows (if you change the options, to display as a scientific calculator). Log base 4 of 27 is the same as log 27 / log 4. You can use logarithms in any base to calculate that - just use the same base for both logarithms.
