The numerical coefficient of the a⁸b² : <u>1.6</u>
<h3>Further explanation </h3>The main composition of algebraic expressions are:
- • 1. phrases / terms
algebraic forms separated by arithmetic operations, can be in the form of numbers, variables or a combination of both
consists of one phrase (monomial) to many phrases (polynomial)
- • 2. variable
is a value that can be changed, its value is unknown, can be in the form of letters, for example, x, y, a, b, etc.
- • 3. constants
is a fixed value, can be a number, which stands alone without variables
- • 4. arithmetic operations
, -, x ,:
- • 5. coefficients
is a number or letter in front of the variable
- • 6. exponent
is a number that shows a repetition in multiplication
Expansion from (a + b)⁶
a⁶ + 6a⁵b + 15a⁴b² + 20a³b³ + 15a²b⁴ + 6ab5 + b⁶
Term that fulfills a⁸b² : 15a⁴b² because :
so :
