Answer 1

The number 2.105 x 10^4 in standard notation is 21050. To convert from scientific notation to standard notation, the decimal point is moved to the right number of places as indicated by the exponent.

Step-by-step explanation:

To convert the number 2.105 x 10^4 from scientific notation to standard notation, you simply need to move the decimal point 4 places to the right, because the exponent on the 10 is positive. Starting with 2.105, moving the decimal four places to the right gives us 21050.

Remember that when you're converting from scientific notation, the exponent tells you the number of places to move the decimal point. A positive exponent indicates a move to the right (for numbers greater than 1), while a negative exponent means the decimal point moves to the left (for numbers less than 1).
