Operations with Exponents
In the following operations with exponents, a and b can be numbers or variables Product of powers To multiply terms with the same base, add the exponents, as in (a m ) (a n ) a m n Quotient of powers To divide terms with the same base, subtract the bottom exponent from the top exponent, as in a m/a n a m n Power of a power To calculate the power of a power, use the same base and multiply the exponents, as in (a m ) n a mn n th root of a power To calculate the root of a power, use the same base and m n am a n divide the power exponent by the root exponent, as in Power of a product To calculate the power of a product of a and b, raise both
to the power and find their product, as in (ab)n a nb n

Absolute Value
Math Handbook
The absolute value of a number, n, is its magnitude, regardless of its sign The absolute value of n is written as n Because magnitudes cannot be less than zero, absolute values always are greater than or equal to zero Examples: 3 3 3 3 4 3 3 units 3 units
V Scientific Notation
A number of the form a 10n is written in scientific notation, where 1 a 10, and n is an integer The base, 10, is raised to a power, n The term a must be less than 10 Power
a 10 n
Term Base 10
Connecting Math to Physics Physicists use scientific notation to express, compare, and calculate with measurements that are greater than 10 or less than 1 For example, the mass of a proton is written as 673 10 28 kg The density of water is written as 1000 103 kg/m3 This shows, using significant digit rules, that this measurement is exactly 1000 to four significant digits However, writing the density of water as 1000 kg/m3 would imply that it has only one significant digit, which is incorrect Scientific notation helps physicists keep accurate track of significant digits Large Numbers Using Positive Exponents
Multiplying by a power of 10 is like moving the decimal point that same number of places to the left (if the power is negative) or right (if the power is positive) To express a large number in scientific notation, first determine the value for a, 1 a 10 Count the number of decimal places from the decimal point in a to the decimal point in the number Use that count as the power of 10 A calculator shows scientific notation with e for exponent, as in 24e 11 24 1011 Some calculators use an E to show the exponent, or there is often a place on the display where the calculator can show smallersized digits representing the exponent Example: Write 7,530,000 in scientific notation The value for a is 753 ( The decimal point is to the right of the first nonzero digit) So the form will be 753 10n 7,530,000 753 106
