A series expansion is a representation of a particular function as a sum of powers in one of its variables, or by a sum of powers of another (usually elementary) function . Here are series expansions (some Maclaurin, some Laurent, and some Puiseux) for a number of common functions.
To convert 112 in Roman Numerals, we will write 112 in the expanded form, i.e. 112 = 100 + 10 + 1 + 1 thereafter replacing the transformed numbers with their respective roman numerals, we get 112 = C + X + I + I = CXII.
To convert 109 in Roman Numerals, we will write 109 in the expanded form, i.e. 109 = 100 + (10 – 1) thereafter replacing the transformed numbers with their respective roman numerals, we get 109 = C + (X – I) = CIX.
In this example, 3 x 1,000 = 3,000; 0 x 100 =0; 4 x 10 = 40; and 7 x 1 = 7. Your expanded format is correct because 3,000+0+40+7=3,047, which is the standard form of the number.
i d a d m m m Sample answer: Since zero has no value, it does not need to be included when writing a number in expanded form.
To simplify a term written in an expanded form, multiply the numbers together and omit all multiplication signs. Note that it is conventional to place the resultant number (called a coefficient) in front of the pronumerals (letters).
(a +b)2 = a2 + 2ab + b2.
