Converting Scientific Notation to Standard Form

The video tutorial covers the concept of scientific notation, explaining how numbers are expressed as a product of a factor and a power of 10. It details the criteria for a number to be in scientific notation, such as the factor being between 1 and 10, and the exponent being an integer. The tutorial also provides examples to help identify whether a number is in scientific notation and explains how to convert numbers from scientific notation to standard form by moving the decimal point based on the exponent's value.

What is the range for the factor in scientific notation?

• Greater than or equal to 1 and less than 10

• Greater than or equal to 0 and less than 10

• Greater than 0 and less than 10

• Greater than 1 and less than or equal to 10

Is the number 5.9 x 10^3 in scientific notation?

• No, because the factor is not an integer.

• Yes, because the factor is between 1 and 10 and the exponent is an integer.

• No, because the factor is not between 1 and 10.

• Yes, because the exponent is positive.
