estimate
answer
an approximation.
If scientists cannot obtain exact numbers, they may rely on estimates, models, or statistical methods to draw conclusions. This approach allows them to make informed inferences based on available data, even if it is incomplete or uncertain. Additionally, they may use qualitative data to support their findings and provide context. Ultimately, such methodologies help maintain scientific rigor while acknowledging limitations in precision.
The exact value of pi is the ratio of the circumference of a circle to its diameter. It cannot be printed exactly in numbers.
It cannot. It can only show square roots which represent only a small proportion of irrational numbers.

Scientists must sometimes rely on estimates when they cannot obtain exact numbers :)

Logic, observation and mathematics. Logic for figuring things out, observation for noticing things, math for getting exact numbers.
No. In fact, a number cannot be both rational and irrational; they're mutually exclusive concepts.
There is no "exact". It is infinite.
The exact numbers cannot be assured but as per the report to congress there were almost 610,042 homeless people in America in January 2013.
That is the correct spelling of "exact" (precise, accurate).
"Approximately exact" is an oxymoron. An answer can be approximate or it can be exact but it cannot be approximately exact.
There are two main situations in which you would estimate:when there is no analytical solution and the only way is to estimate a solution using iteration,when an exact answer is not required or the time or effort required to obtain an exact answer cannot be justified by the improved precision.
