Final answer:
The fourteenth number after the decimal point in pi is 5, which is not reflected in any of the provided options. Pi is an irrational number that extends infinitely without repetition, so you must look to a detailed sequence to identify specific digits beyond the common approximation of 3.14.
Step-by-step explanation:
The fourteenth number of pi would be the digit in the fourteenth decimal place, counting from after the decimal point. Since pi is often approximated as 3.14, and the exact value extends infinitely without repetition, we need to consider more digits to answer this question. The sequence of pi begins with 3.141592653589793, so the fourteenth decimal place is 5. Therefore, none of the options given (a) 3,1415, (b) 3,1416, (c) 3,1446 accurately represent the fourteenth number of pi. The closest correct digit to the fourteenth place after the decimal in 3.141592653589793 is 5, but it is not represented in any of the options provided.
To understand how to deal with scientific notation or to identify significant figures, you can consider various examples and rules related to these mathematical concepts. For instance:
- Expressing numbers in scientific notation simplifies large or small numbers by using powers of ten, which can be especially useful in fields like physics or engineering.
- The concept of significant figures helps in determining the precision of a measurement or calculation.
