Algebra Formulas for Class 9
For class 9 Logarithms formulas are very useful. They are helpful for the computation of highly complex problems of multiplication and division. The exponential form of 32 = 9 can easily be transformed into logarithmic form as log3 9 = 2. Also, complex multiplication and division can easily be converted to addition and subtraction by following the logarithmic formulas.
Important log algebraic formulas that are most commonly used are discussed below:
- loga (xy) = loga x + loga y
- loga (x/y) = loga x – loga y
- loga xm = m loga x
- loga a = 1
- loga 1 = 0
Algebra Formulas
Algebra Formulas are the basic formulas that are used to simplify algebraic expressions. Algebraic Formulas form the basis for solving various complex problems. Algebraic Formulas help solve algebraic equations, quadratic equations, polynomials, trigonometry equations, probability questions, and others.
An identity is a true equation for any values assigned to the variables. Algebraic Identities are used to solve various equations. For Algebraic Identities, L.H.S is always equal to R.H.S.
