product of a number and one or more variables (which may be raised to powers). For example‚ 3x‚ – 4yz‚ 7a2 b3 . Coefficients In a term that is the product of a number and one or more variables‚ the number is called the numerical coefficient or simply the coefficient. For example‚ in the term –2b3‚ the coefficient is –2 and the variable part is b3. Like and unlike algebraic terms Like algebraic terms are defined as those terms which are represented by the same algebraic symbol‚ regardless of

In mathematics‚ an algebraic expression is an expression built up from constants‚ variables‚ and a finite number of algebraic operations (addition‚ subtraction‚ multiplication‚ division and exponentiation by an exponent that is a rational number).[1] For example‚ is an algebraic expression. Since taking the square root is the same as raising to the power ‚ is also an algebraic expression. A rational expression is an expression that may be rewritten to a rational fraction by using the properties
