Question

put -311 in  scientific notation

Answer 1

To put a number in scientific notation, we multiply a base number between 1 and 10 by 10ⁿ.  n is the number of places we move the decimal by to make the number between 1 and 10.  If n is positive, the number is greater than 1.  If n is negative, the number is between 0 and 1.

 

 

-311 = -3.11 × 10²
