# Scientific Notation

To write numbers in scientific notation N = u . d d d Ã— 10P with only the units-digit to the left of the decimal and all others following it â€“ and the power P is the position power for the number N.

Multiply and Divide with Scientific Notation and express the result in scientific notation:

Example 1:

 a) (1.23 Ã— 103 ) Ã— (2.32 Ã— 10 4 ) = (1.23 Ã— 2.35 ) Ã— (103 Ã— 10 4 ) Commutative property = 2.8905 Ã— 10 7 Multiply coefficients and add exponents

 b) Write as separate fractions. Divide coefficients and subtract exponents.

 c) Write as separate fractions. Divide coefficients and subtract exponents. Round answer to 3 decimals.

 d) (4.53 Ã— 109 ) Ã— (7.32 Ã— 10 â€“ 4 ) = (4.53 Ã— 7.32) Ã— (109 Ã— 10 â€“ 4) Apply commutative property. = 33.1596 Ã— 105 Multiply coefficients and add exponents = (3.31596 Ã— 101) Ã— 105 Rewrite first term in scientific notation = 3.31596 Ã— (101 Ã— 105) Regroup powers. = 3.31596 Ã— 106 Add exponents for scientific notation.
