It means that the correct value could be anything between 243500 and 244500 square kilometers.
it mean signs
If you mean "How many significant figures are there in 314.721 meters then the answer is 6.
Probably "number of significant figures = 2".
The greater the number of significant figures, the greater the precision. Each significant figure increases the precision by a factor of ten. For example pi = 3.14 is accurate to 3 significant figures, while pi = 3.14159 with 6 significant figures is a more accurate representation.
There would be five. The only time you do not count figures as significant is if they are zeroes behind a decimal, but before any other figure. Ex/ 0.000501 only has three significant figures, while 1.000501 has seven.
Exactly what you typed. 144.78 rounded to 2 decimal places is 144.78. You may mean significant figures, in which case it would be 1.4*10^3 (2 significant figures).
It has 4 significant figures.0.007080 has four significant digits.
if you mean PI squared + PI squared / by 2 then that is.... 4.9298 solved on paper ... BUT if you mean what you said, the answer is YUMMY!
n^3 mean a number Squared by 3
If you mean ex squared, the answer is e2x
If you mean a2 x a2... the answer is a4
A significant figure refers to the digits in a number that contribute to its precision, including all non-zero digits, any zeros between significant digits, and trailing zeros in a decimal number. For example, in the number 0.00456, the significant figures are 4, 5, and 6, making three significant figures. The concept is important in scientific measurements to convey the accuracy of the data. Understanding significant figures helps in maintaining consistency and reliability in calculations and reporting results.
