In math, expanded form can refer to any type of expression, equation or notation that is completely broken down into its individual parts. Expanded form is commonly used in teaching students place value and factoring.
Know MoreIn discussion of place value, expanded form is when a number is broken down into each place value with an addition sign placed between each number. For example, 356 would be 300+50+6 in expanded form. When an expression is factored, it changes the expression into expanded form. x^{2}-4 would factor into the expanded form of (x-2)(x+2). The expanded form of quadratic equations is often more useful in graphing than the standard form.
Learn MoreTo solve rational equations, use the common denominator to resolve all the fractions. Removing the denominators makes it much easier to deal with the remaining terms, converting the problem into a simpler equation.
Full Answer >The prime factors of 50 are 2 and 5, with the rest of its factors not being prime numbers. A factor is any number that can be divided evenly into the base number of interest, but only some factors are also prime numbers.
Full Answer >In math, properties demonstrate general rules that are used in calculations. The most commonly used properties in day-to-day math are the properties of addition and multiplication. The commutative property of addition, for example, states that no matter how you order the numbers when adding, the result is the same.
Full Answer >The mathematical property associated with ln x + ln y is the product rule of natural logarithms, expressed as ln(x ? y) = ln(x) + ln(y). The rule is used for adding together any two logarithm expressions that are to the same base, which for the natural logarithm is the base e.
