Scientific Notation

To write expanded numbers in scientific notation N = u . d d d Ã— 10^P with only the units-digit to the left of the decimal and all others following the decimal. → The power P is the position power for the left-most nonzero digit of the number N.

Example 1:

Express expanded form numbers in scientific notation:

a) 8,756 = 8.756 Ã— 10³ in scientific notation..

To write scientific notation number u . d d d Ã— 10^P= N in expanded form place the units-digit in the the position power for the number N with all others following, filling with zeros to the decimal.

Example 2:

Express scientific notation numbers in expanded form:

b) 9.43 Ã—10⁵ = 943,000
