Scientific Notation Concepts and Conversions

The video tutorial explains how to write numbers in scientific notation, which involves expressing numbers in the form of 'A x 10^B', where 'A' is the significand and must be between 1 and 10. It demonstrates converting both large and small numbers into scientific notation, highlighting the placement of the decimal point and determining the exponent. The tutorial also provides tips on remembering whether the exponent should be positive or negative based on the size of the original number.

What is the form of a number in scientific notation?

• A divided by 10 raised to the power of B

• A minus 10 raised to the power of B

• A plus 10 raised to the power of B

• A times 10 raised to the power of B
