Question 7 • Physical Science Sem 1 (2003310) BCPS 2026-27

Which describes the correct procedure when converting a number from scientific notation to standard notation?

Answer
A
If the power of 10 is positive, move the decimal point to the left.
B
If the power of 10 is positive, move the decimal point to the right.
C
If the number being converted is greater than 10, move the decimal point to the left.
D
If the number being converted is greater than 10, move the decimal point to the right.

Explanation

In scientific notation, a positive exponent means the number is multiplied by 10 repeatedly. To write it in standard notation, move the decimal point to the right by the number of places shown by the exponent. So the correct choice is “If the power of 10 is positive, move the decimal point to the right.”
